GM didn't keep specific records of what optional equipment items were on each car. You can figure basic percentages when looking at the total number of items but the only specific numbers are by RPO code.
There were 23,646 1990 cars, 7,630 of those were ragtops.
These numbers are for all 1990 cars:
2,956 red cars
3,397 Red Leather Sport Seats
20,419 power passenger seats (all colors)
4,161 black convertible tops
8,100 6-speed cars (may include the ZR-1 cars??)
22,497 C68 electronic A/C system
L98? All of them except for the 3,049 1990 ZR-1's
7,576 cars got FX3 Selective Ride Control. But RPO Z51 had FX3 as part of that package and all ZR-1's had FX3 as part of their suspension.
Have you found the Service Parts Identification sticker" It will be either under the console lid or under the passenger side rear storage compartment lid. You can look here for the full list of RPO codes and their description.
