Didn't want to high-jack another thread so I started my own....

This is great information, but now I'm really confused. OK according to my build sheet, I have the following options: ZR1, FX3, Z51, FE7, so which combination of the specs is correct for my 1990?

The specs that are listed for "ZR-1" under 1990 are the ones. RPO's FX3 and Z51 are on all '90 ZR-1's.
