I was going to replace the front rotors on my 1993 corvette but the auto parts store asked me what system I had, a J55 of a JL9. Where do I find this information. Its also a LT1 coupe.

Measure rotor diameter.Its either 12 or 13 inches.You can also call the local Chevrolet dealership & give them your VIN number & they might be able to tell you.Get quality parts if you drive your vette like its meant to be driven

Usually the RPO code list is under the center arm rest door. Also have heard it could be under the left rear storage bin.
