I've Got it Covered! (Part 2)

In the first installment of "I've Got it Covered!", I re-upholstered the back seat top and bottom.  This was fairly difficult but nowhere near as difficult as the front seats.  Firstly there are four sections to the front, instead of two, including the complexity of the seat hinge/latch mechanism in the seat back and the seat tracks on the seat bottom.  Additionally, the seat backs have a clipped-on back card and extra high-density foam padding on the back.

So, before I could even begin to re-upholster the front seats, I had to break them down first.  This involves first removing the plastic hinge covers from both sides and then removing the hing pins from the pivot shafts attached to the seat bottom.  The fun part here is that you have to pry the longer hinge arm away from the pivot and then work the shorter hinge arm away from it's pivot.

The seat bumpers.  These were removed first followed by the hinge covers.


Once the seat back is separated from the seat base, the seat tracks were removed from the underside of the seat base.  This involves removing three springs and four special screws.  To get to the screws, you have to shift the track forward and back.  The tracks then just lift off with or without the connecting rod between left and right.  After the tracks are removed the seat base upholstery can be removed.  Removing upholstery on these seats basically just involves cutting the dozens of hog rings.  I used a small bolt-cutter but they make a hog ring cutter just for this purpose.  Once all of the hog rings are removed, the fabric could be folded up and away from the frame... well... sort of.  Still remaining are "listing wires" that attach the center section of the upholstery to the frame.  These wires give the top and bottom seat centers a contoured shape.  Unfortunately, they are attached through the seat foam and to the frame with several more hog rings that needed to be cut.  Finally, the fabric and foam can be removed from the frame.  However, even after all of this, the frame isn't officially stripped because there are also jute pads, the frame listing wires, and burlap with wires weaved through it all still hog-ringed to the frame.  After all of these parts are cut away, only THEN can the frame be cleaned and repainted.

This whole stripping process was then repeated on the seat back frame.  However, the seat back also contains a mechanism for the seat latch in addition to high density foam pads glued to the back panel of the seat.  With all of this removed, the seat back could then be cleaned and painted.

I think that the optimal method for cleaning the seat frames would have been chelation, media blast, or dipping.  As it was, all I had at my disposal for the task was my drill, spinning a 2" wire cone brush.  My goal was to knock off loose rust, paint, and debris.  I then coated the frames with Ospho and left them to sit in the sun.  After it dried, I rinsed them with water and a scrub brush, dried them with a heat gun, and then rubbed them down with lacquer thinner.  I followed up with a coating of self-etching primer and finally several coats of semi-gloss engine enamel.

One of my many visions for this car is a set of headrests.  This poses a bit of a problem.  Firstly, although headrests were an option in 1968, they were rarely purchased.  This means that an original set of 1968 headrests are very expensive, on the order of $400 a set expensive and that's before new upholstery and brackets.

In 1969, headrests became more standard and were shared by the Mercury Cougar (and a few other Ford/Mercury/Lincoln models) and the best news yet, they are reproduced today.  However, the difference between 1968 and 1969 headrests are many, including the fact that the 68 headrests had two posts instead of one flat bar.  One option that has that 68 look and feel is the "Sport Seat Style" headrests available at the various vendors.  Still at $300 a set, they're out of my ballpark.  A less expensive option are the more generic "Headrest Conversion" available from the vendors for around $200, a more viable option but appear to be non-adjustable which is a bit too cheesy even for me.  So, the clear winner in my mind was the 1969 style headrest.
The ultimate goal

As of this writing, my intention is to find good original ones from a Mustang or Cougar at a price below $80 apiece which happens to be the repro price (minus upholstery).  However, just because I don't yet have the headrests, doesn't mean that I can prepare for them.  The problem is that although the 1968 and 1969 seat frames are damned-near identical, the headrest bracing is way different with the 1969 seat having a lot more structural bracing at the top of the seat back frame as the picture to the right shows taken of a 69 Cougar seat back and headrest.  So, I needed to simulate that option while providing legitimate structural integrity for the headrest so it doesn't just break away in the event of an actual accident.  Fortunately, the sliding brackets for the 69 headrest are also reproduced and are inexpensive at $20 each so I bought a pair.

After a bit of thought and lots of measuring and researching as many images of 69 seat backs as I could find, I came up with a compromise.  I think that this solution is not nearly as strong as the "real" 69 frame but is much better than nothing IMHO.  The pictures below are pretty self-explanatory but basically, I just welded a 1/8" steel plate to a 1" square tubing.  I notched the tubing to bring the headrest bracket into alignment with where it needed to sit in the seat frame.  The four holes in just align with the existing holes in the frame and are set to center the plate with the center of the seat back.  Four 1/4" captive nuts are welded to the plate for the bracket to attach to.  The bracket was then painted and bolted to the frame.

The rest of the seat back could then be assembled including re-installing the seat latch mechanism and using contact adhesive to re-attach the high-density foam pads.   Since the front seat burlap with integral wires were pretty much rotted to uselessness, I opted to use two layers of burlap to isolate the foam from the springs.  The jute edge padding was also beyond use so I hog-ringed a strip of 1/2" medium density foam around the edge of the frame and then hog-ringed the original listing wire to the springs.   I cut splits in the foam every 4" or so because the listing wires for the upholstery are hog-ringed through the foam and onto the thick listing wires attached to the frame.  The upholstery listing wires were cut out of the original covers and threaded through the sleeves in the new ones.

The real work can then be started; pushing hog rings around the listing wires, pushed through the foam slits, and clamped to the wires on the seat frame.  This is by far, the most difficult part of the re-upholstery job in my opinion and I really didn't "get it" until I was practically on the last seat.

The process of hog ringing the upholstery to the frame was really not all that difficult although it could, at times, be one of the more physically taxing tasks since the upholstery had to be pulled taut, while massaging the foam to take up the slack and get the wrinkles out while making sure the edge piping is correctly aligned with the seat edges.

The front seat backs were finished up by punching holes to make room for the back card clips and the latch release lever shaft on the side of the seat.  The card was then popped on completing the seat back.

Done. Back.

Done. Front.  Not too thrilled with the listing wire job on this one.

The process was then repeated generally the same for the seat bottoms which were finished up by cutting slots for the hinge posts and latch bracket.

Seat bottom hog rings.

Done.  Note the unevenness of the listing wires again.  I'm thinking every 3 inches or so is what it would take to get this  perfect on both the fabric and seat frame wires.

Holes punched for the hinge pivots.

The seat back was then re-united with the bottom by first inserting the short hinge onto its post and then prying the long side onto its post while trying not to drive a hole into the new fabric.  Finally, the seat tracks were lubricated with some lithium grease and missing springs were replaced and the connecting rod was adjusted.  Normally, the hinge covers would be replaced at this point, but I'm still working on repainting my originals so they aren't pictured here.  Also, the seat bumpers were replaced (not shown).  They get pretty beat up during their lives and inexpensive repros are available.

Back and bottom reunited.

Seat tracks installed.

The seats were next re-installed in the car and the red interior is history.

Done!
You might notice the lack of headrest holes.  No point in cutting holes if I don't have them yet but the brackets are there for when I do.

  1. Great job. The interior looks really nice now. Those headrests are a must. Many times I found myself looking at the rear view mirror while braking to make sure the car behind me was braking too, and at a safe distance. I've been really thinking about installing those too.

    1. Thanks Ivan. I already have neck problems from being rear-ended about 15 years ago and am not looking forward to doing it again.

  2. Wow Alex! That finished interior is stunning. Again, your detailing of the process is excellent and will come in handy whenever I get to that point, especially the head rest addition. I will guarantee you will not get strange looks at your 'vert any more!

  4. Bravo my friend! I an so diggin' that interior and exterior color combo! You have definitely tackled the reskin work like a true pro!

  5. I agree with Sven, that is a beautiful color combination Alex. You done good :)

    P.S. Somewhere in my notes, I have an article by a guy who put shoulder harnesses in a 68 convertible using seat belts out of a van. It was such a nice install, I actually bought a pair of brand new ones I found on ebay. Hope to integrate them into the car someday. Seems like a good add-on to go with the head rests.

    1. Thanks RJ! Yes, shoulder belts in the plans. I've even put an extra anchor on the inner rocker for the reel on each side but will likely hide the reels inside the rear quarters. The important thing with shoulder belts is to install them in such a way that they don't compress your spine too much if you crash so placing the upper mounts as high as possible is the safest option. Still, better to compress your spine than to smash your face?

  6. Alex, I have a "blogger" question for you. I gave my blog title to a guy who wanted to look at it. When he Googled it, your blog came up all over the place. Did you do something to help your blog be more visible on a search? Whatever it is, I need to do that too. Thanks.

    1. The only things I did to make the blog searchable was on the blog Settings->Basic->Privacy I set Google's "Add your blog to our listings" to Yes, and "Let Search Engines Fine Your Blog" to Yes. Also, "Blog Readers" to Anybody. On Settings->Other, my "Allow Blog Feed" is set to Short and "Adult Content" is No. I think that these settings plus just the longevity of the blog (4 years now and 126 posts), Google's engine has had lots of time to index it.

  8. Hey there Alex... another fine piece of work. Not that I expect anything less :).

    Is that just the standard parchment interior colour?

    Looking soooo much like the colour combo I will end up with!

    1. Hey Mike! Thanks. Yeah, that's the standard 68 parchment. I think some might call it "light parchment".
