Hi everyone i just recently picked up an 87 monte ss and the guy was dead set that it had a gn rear end im not so sure it does are there any easy ways to tell the 8.5 apart from the stock 7.5 without pulling the cover? Thanks for your help
Post a picture. I'll tell you. For one thing, 8.5's have square "ear" tabs, 7.5's have "fang" tabs. The 8.5 cover is also more "round". The 7.5 cover is kind of rectangular.
