Iroc rear discs
I haven't been able to find an answer to this question one way or another...
Did rear disc brakes come standard on 1986 and 1987 irocs or were they an option when the iroc package was ordered?
I'm looking at an 87 with rear drums and am not sure if the axle is original.
Thanks for any help!

my 87 had a factory installed borg warner 9-bolt with disc brakes, i beleive it was an option, i dont think rear discs were standard because i have had 2 previous 87 irocs and both were drum rears.
