I was doing some brake work on my 1989 trans am with rear drum brakes. I still have the drum brakes and got new rotors, calipers, brake hoses, brake lines, etc for the front. But the threads on my proportional valve are cross threaded now, I guess I did that, but I can't find a new one to replace it with that is a direct fit. I need help, anybody have any ideas? Thanks.

 

I had this exact problem and I couldn't find a replacement one. I ended up getting a disc/disc proportioning valve from amazon. Seems like no one has a disc/drum anywhere.
