disc brake swap

I have an 89 GTA with a nine bolt. I am buying a 10 bolt that is rear drum and I need to know if the proportioning valve off of the nine bolt will work on the ten bolt. I also have a post in parts wanted looking for the caliper brackets for the ten bolt so if anyone has some please check it out.

You're swapping the brakes over, right? The prop valve will then match the brakes so you will be fine....the prop valve will have nothing to do with what type of rear you run, only the brakes.

What caliper brackets do you need?
