The frames should be the same. You need a curved tool to slide down the headrest mounting tubes, to release the retaining tangs. Other than that, most of the tools are common wrenches, and screw drivers. You will have to check the circuits for the lumbar supports. The switches on the donor seat are probably different in number or type. If you swap your foam, and cover to the 96 frame, you can probably keep the lumbar parts and switches from your seat.
There are probably a couple of strips that hold the seams in place on the foam, I am not sure how they attach, but could be Velcro. Generally the seat skin perimeters are held in place by strips that fit over the frame.
The seats are generally identical, but you may have different connectors.
When you take the 96 seat apart, and compare it with your original seat, most of it will become self evident.
