The only way I could make it work on my 95 was to keep the bouncy seat's cushion (cloth) and graft my seat back section onto the whole lower frame. I did not like it and switched the driver's side back to stock, non-bouncy. The fixed position of the bouncy base just didn't work for me.

The passenger side bouncy base is easy and worth it to the passenger as it sacrifices nothing in adjustability or seat cushion mis-match.
