Curiosity got the best of me, so I got to digging.
Found this at corvsport.com/1992-c4-corvette/

The ZR-1 Corvette received additional badges on its front fenders, and all Corvettes (base coupe, convertible and ZR-1 variants) received twin exhaust outlets that were rectangular in shape. For 1992, General Motors made the decision to reduce the formerly standard six-way power passenger seat to an extra-cost option. This decision was short-lived and returned as a standard option in 1993.

This is quite a curiosity to me, but looks like the power passenger seat may have been an option on the '92's. If this information is correct, I guess we still "learn something everyday"!!
