Switch gears

I have a 1989 coupe that's been swap to a 5.0 originally was a 2.3 and I want to upgrade my rear end will this fit? If so will this be everything I need to convert it?

If it still has the factory rear end from the 2.3, you've got a 7.5" rear end. - Jody last year

According to my research, your car, if original, should have the 7.5 rear end. If so, the gear set will not work. You would have to swap in an 8.8 rear axle. As noted in the information from LMR the gear set will only fit the 8.8.

Good Luck!

If you have a 8.8 rear end yes.

Also, if you're fortunate enough to still have the tag on the differential cover.... On the bottom line there will be a 3 digit code in the middle (example: 75A or 88A), 75 is a 7.5" and 88 is a 8.8".

Hope this helps
