OK, success! First off, I'm not sure you need to remove the vinyl here, as
@wchevron suggested. I wanted to just to make sure I wasn't going to cut into something with the wrong spacing, so for me it gave me the confidence to cut into my vinyl seat backs. For reference if you go this route, I suggest the following video:
If you are going to remove the vinyl, I suggest two sets of pliers (I used two needle-nose pliers), and some upholstry tacks / tool. I used
this from CCOT, which I noticed is a Pittsburgh, so check your
harbor freight.
Onto the photos. First off, I have a '78 model year (built oct '77), and my headrests have about a 5" gap between posts:
I removed the vinyl seatback so I could check to see if the spacing was indeed 5" on the top of the seat. To do this I first removed the entire seatback, and removed the staples along the bottom. Do this on a hot day for ease of use... I tried this in March and abandoned it until now (BTW, thanks for the push to get this project done!). Don't forget the additional tacks about 2/3rd of the way up on the seat back:
Once the vinyl was off, I was able to check the top. Sure enough, after poking some holes in the foam with my finger, the headrest slid right in. I found that once it clicked in, I had to push it forward and slide it up to get it out (you can also push it forward and slide it down to seat it lower on the seat). Also, on one side there is this little tube that seems to hold the post, and it looks like this is what the escutcheons go around. This pipe was not on the opposing side, so I don't know if it was made this way intentionally, or if my seatback is missing one (we'll find out when I do the drivers side). I did a test-fit of the escutcheon before re-attaching the vinyl:
No "tube" in the other hole:
BTW, got these
escutcheons from Proffits in you need em. So far they seem to be sturdy enough, but they are 3d-printed.
I took my time locating holes for the vinyl once I got things re-assembled. I use a knife and scissors, and checked with my fingers to locate the escutcheons. Lucky for me even though the tube wasnt in the other side, the hard foam had a hole for it, so it holds itself in nicely. And all done!
Hope that's helpful! Now, on to the drivers side
