I believe the OP wants a 8.5 10 bolt from a GN that would fit a later G Body Monte Carlo. I may be mistaken but Bruno might be thinking he wants a first gen Monte rear. Just trying to clarify just in case. If I'm wrong ignore me.
Ignore you ?No way,you are a very smart guy here ,but just to explain I have both the 8.5 from a 71 and also one from a 87 GN,both with 3.73 gears.Bruno.
Hi Bruno, I completely lost track of the thread. The guy is still looking for an 8.5 for a gbody monte. If you still have one...or anyone else. Still interested.
