Was wondering i have an 89 camaro that has a regular rear end .. 2.73 gears. Would this differential bolt up to my existing setup? https://www.justdifferentials.com/st...cat=172&page=1


Thanks for your help!

It might.... you have an 89, which has about a 80% chance of having 26-spline axles. Only a few 89s got the new style rears.

If I was you, I'd pull an axle and check, BEFORE ordering parts, pulling the axles, and THEN discovering it won't work.

Of course, if it was my car, and I just up and ordered a 28-spline part, the rear would FIND A WAY to make itself 26-splines; and vice-versa. Just the kind of world I live in. So I always look at stuff before I buy, try to catch it in the act, so it can't make itself wrong for me.

But who knows, your luck might be better than mine.

It CERTAINLY will not work with your existing 2-series gears. You have 2.73s, and as that clearly states, it's for 3.23 and up. 2.73 is not in the range of 3.23 and up.

 

Nope, you'd need a series 2 carrier.. You have 2.73 gears... If you stepped up to 3.23 gears, you could use that unit.

 

No for the reasons in the previous Post and you might have 26 spline axle shafts. 89 was a change over year, but that 2:73 ratio had good chance of havings the 26 spline shafts even into 1990.
