If I wanted to install a 9 inch or a 12 bolt in my 94 T/a, from another vehicle- what would be required for me to do it?

I suppose I'd have to have the axle tubes modified, and buy new axles, and do the obvious rebuild? Has anybody done this before, and if so- what did it cost you?

Easiest way would be to find a 93-97 F-Body with that 12 bolt or 9"... Otherwise you'd need more work and we all know that's not cool. Did you find a sweet deal on something or do you just not like what the aftermarket has? I'm going for a Currie 9" once funds allow!! Sweeeeet! Goodluck! Nice to see you on the boards too man, hopefully you can make the national event in July here in MI.

 

There are no factory 12 bolt or 9" diffs that are a direct bolt in. You'd need to find some way to attach the torque arm or convert your rear suspension to ladder bars or a 4-link system.

The only way you'll find one that's a direct bolt in is to buy an aftermarket diff that's designed for an F-body.

Doing a rear suspension conversion to use a junkyard diff can cost more than buying an aftermarket diff.
