Re: 90 camaro, 9 bolt or 10 bolt?
99% likely a 10-bolt, but after 20+- years, there is no guarantee your car hasn't changed. Never assume anything.
Look under the back of the car, at the rear end cover. 10 bolt heads = a 10 bolt
9 bolt heads = a......Can you guess? A NINE bolt!

Who would have thought that the name actually referred to something.

The last production year that had a 9 bolt was 1989.
