Default 1979 TA WS6 proportioning valve rebuild?

Really long story short, I need to rebuild the original brake proportioning valve for my car. Having a hard time finding the parts. White Post wants $175 and I'm not ready to spend that kind of money.

OPGI sells a switch for a G-body. Assuming switches are generic?

The only other serviceable part would be the O-rings, correct? Springs should be ok?

Help please!

Thanks,
Jim

With the ws6 package, this should be a disc/disc car correct?

If that's correct, I'd verify the shuttle valve internally is operating correctly. In general I don't think you want to open it up to get to that. if the shuttle is not operating correctly, I wouldn't spend a dime on the rebuild.

Jason-

Ok, so the long story is this, there are two long bolts that hold the valve to the mounting bracket. One came out fine, the other broke in half, inside the hole going through the valve. My dad heated the valve to free the bolt up. Hence, it needs to come apart to replace the O-rings.

I would be afraid what may have happened to the shuttle valve depending on how much heat was put into it.
