I have seen a few people post about seats...
The seats on the '90 - '93 cars are the same, with the exception of the 1990 having controls on both bolsters. In 1991, they removed the controls on the entry side of the seat.
The '94 & '95 have the same design seats (except for minute details) to better accommodate a (read wwiiddeerr

) selection of butts.
I will agree, other than the later seats looking kind of cool, the first generation of seats were very form fitting. Better than any Corvette built since, in my opinion.
