I have a 10 bolt 1984 rear I took out. Is it a 7.5 26 spline? Can I put in a new differental. Can this rear be beefed up?I put in a 89 9 bolt 327 put wanted to build a back up. The one laying in my garrage has 308 gears.

 

did you do a search? i think someone else ask the same question.

 

Yes I did under "84 rear end" I'll try 26 spline hoping that it pertains to my rear. I did put energy and will again put effort in a search. I never try to waste moderators time.

 

3.08 gears use a two series carrier. Anything higher than 3.08 requires a three series carrier.

 

you should have a 7.5 ten bolt with 26 spline axles, 28 spline came out in late 89. the 7.5 and 7.62 ring gear interchange so don't get hung up on that. you can weld the tubes and run a rear brace and increase strength quite a bit. you can swap carriers from any other 7.5/7.62 ten bolt rear and axles as well if you need to.
