I'm looking for the thread that has all of the 9" and/or 12 bolt diff swap info. The 7.5 probably won't live long behind the motor I'm building. Any ideas/suggestions?

Thanks

 

Buy aftermarket bolt in 9" or 12 bolt. Take out 7.5" diff, install new diff.

 

hop on the drag board, i wrote a very nice step by step assembly process for a moser 9" that has never been stickied but I send a lot of people to that.

 

I run a 9" in my 86 Camaro... I deleted the torque arm and use the South Side Machiene lift bars along with no stock lower control arms and QA1 coil overs behind the axel. Works for me

I like the Moser 9" factory bolt in myself.

 

yes, just remove the bolts that hold in rearend and install new one. It is very easy.

 

Ditto on going aftermarket. I picked up a 9", cut all the brackets off, cut the factory ones off and transfered the F-Body brackets to the 9". Took forever, you have to be careful welding. Not to mention making a bracket for the torque arm unless you go with ladder bars or something of the sort. Take it from me. It will cost about the same in the end. I've had to get adjustable control arms and torque arm to account for the slight differences in all the brackets.

 

What about driveshafts/u-joints with the aftermarket rears? 9 inch, 12 bolt....

 

You buy adapter u-joints to convert the GM 3R u-joint to a 1310, 1330 or 1350 that the 12 bolt or 9" will use.

 

Thanks! Will the length stay the driveshaft length stay the same? The reason that I ask is that I have a thirdgen aluminum driveshaft and a fourthgen aluminum shaft that I can use.....

 

nice writeup on the drag board would have answered that question


and yes.

 

What's a diff swap and u-joints got to do with drag racing? It would have fit better in the Transmission and Drivetrain board.

 

Thanks guys.

Later, Kevin

 

YUCK!! If your spending the money on a 9" or 12 bolt. Spend the extra cash on a custom driveshaft and 1350 u-joints. You will not break anything then!

 

well your hood pics would have done better on the body board

Just stating that I already answered the u-joint questions and diff swap questions as the 9" is mainly drag related also.
