Could someone please tell me if:
1) In 1988 all IROC-Z (Borg Warner 9bolt) would have came with an Aluminum Drive Shaft?
2) What the RPO Code is for an Aluminum Drive Shaft?
TIA!

Questions:
#1 NO
#2 JG1

 

Would this RPO code still be the same in 92?

yes, JG1 indicated an aluminum shaft every year it was available.

 

Thanks again!
