What was available in the back of 85-87 Irocs? The one i am looking at has Aluminum drums, if that means anything. I think its either an 85 or an 87 unless someone switched the hatch(no brake light outside). It has a wonderbar and no power options.

Gear ratios available?
Were all Irocs posi ?
Did alum drums mean anything specific?

Thanks!

U can find the gear ratios here https://www.thirdgen.org/newdesign/tech/techdb.shtml yes they were all posi, and drum brakes just means that the optional 4 wheel disc brakes were not ordered.

I don't think all IROC's were posi. If it were, then the window sticker of my car would show that as part of the IROC package and not listed as a seperate item. It shows it as G80 Limited Slip Differential $100.
