Can you take the tilt and slide passenger seat option that is in the Sufire's and adapt it to work on the cavalier seats? my 98 Z24 doesnt slide forward after you tilt the seat back up, but the 96 Sunfire GT I looked at did, and I wish my seat would.
Just swap the seats, it would be much easier.
Also the grand am seats and grand prix seats fit to with some minor modification.
with some custom brackets, you can fit rsx seats in as well... alittle wider than stock, but they feel great, and look great too.
