OK,

Bought a 1986 Trans Am. Originally a rear disc brake car. Previous owners thought the disc brakes in the rear was a bad design so they scrapped it out and put in a drum rear from a 1985 Trans am. Only thing is they didn't know the proportioning valve (combination valve) needed to be changed out as well.
Looking for a decent 10 bolt disc rear has proved to be more $$$ than I am looking to spend right now. The cheaper alternative is to go with the proportioning valve for a drum rear to get the car road worthy.

So anyone that may have done a swap to a disc rear and has a valve from the drum setup I would be interested in it. Shoot me an offer.

Not looking to sell the disc valve thats in it right now as I would eventually like to get the car back to disc brakes. This is a temporary way to get the car on the road.

 

I have one from an '86 T/A....PM'd you.

 

Should be good now!
Thanks to those that replied!
