So as it turns out, the solution to my problem was very simple. I just swapped over the 93 seat foam & fabric to my 96 seat frame. I started with the passenger seat so if I ran into any issues I could still drive the truck home from work. I had to make some minor adjustments here and there though. The side bolsters were a little different as well as the width of the seat bottom. All in all it turned out fantastic and I can't wait to finish it up by doing the drivers seat. I took a few pictures during the repair but had to stop so I could finish and get back to working on other peoples cars.....
This is the drivers seat out of the 93. The tracks are different, plus there's no buckle.
This is my drivers seat in the 96. Crappy fake leather covers and no padding or support. You can see the finished seat on the other side.
This is my 96 frame with the seat back & foam removed.
Here's the foam from the 96 seat. You can see the tears in the bolsters as well as the center back.
Here is where I had to modify the foam a little. The bolster shape is a little different so I had to cut it so the frame would slide in. I worked rather well.
Here's the seat after I installed it in the 4runner. It matches the interior pretty well and the seat is very comfortable. I wish I could have driven home on it.
The best thing I found was that the headrest posts are the same width and distance apart so I reused the the post mounts from my 96 seat since the 93 post mounts don't work with the 96 frame.
I didn't get to take pictures of the seat bottom transfer but it's pretty easy. I'll post some more pictures tomorrow of my drivers seat project.
