how much abuse will a 9 bolt take thanks

 

They are stronger than the 10 bolt, but you can't get parts for them. Good luck with it. Some people have hit 11's. Depends on the car and traction.

 

You can get all the parts you want. Just not as easily going to whatever store you want to. And you'll pay a little more $, for the 10 bolt "equivalent" part.

http://9bolt.com/ is one place & I believe Australia is STILL using the M78 center section!

 

Thanks guys is 9 bolt.com only place that has parts

 

I have a spare carrier that is worn if you need parts. I am trying to get out of 9 bolts. I also have a set of 3.45 gears.

 

No thanks i was just wondering if it was worth putting new gears in or not

 

I think they are, but not the cheapest to rebuild.

You could just get a complete LS1 rear end for a strong differential & bigger brakes.

 

They can be if your posi is still good. If not, go with a 4th gen rear.

 

Raytech is a lot cheaper for bearings/seals/shims.
