I have finished changing out rear ends for a limited slip 9 bolt with rear disk brakes. Old rear end had drum. Anyone point me in the right direction for a proportioning valve, manual or new onw for 4 wheel disk. I have a manual valve, but have questions on if it will work.

 

AJB, What rear end did you use ? I have a 82 Z28 with a 10 bolt and drums. I'm needing to change it out for disk.

 

i had a 10 bolt with drums, now I have a 9 bolt with disk. Later I am going to change gears. I have 2.77 in now, I want to go to 3.73

 

Where did you get it ? And what car should I be looking for in the junk yards ?

 

I got it from a guy here on thirdgen. I had to drive a couple hours to get it. Cars that have it, I BELIEVE, are the fbirds and transams. They are the common ones, I think that a few camaros have them. go here to this link and look at the tech data. You are looking for the astricks on the right part of the screen. Hope that this helps you.
