I installed a Hydro boost system into my 88 K5 blazer from a 1986 K30 1031 military truck.
everything is new, but I'm unable to find a new Brake Proportioning Valve.

The hard lines from my 88, proportioning valve to the K30 hydro boost master cylinder fit perfectly

Is the stock valve in my blazer the same as the one from the 86 K30? I don't think so but I wanted to make sure.

both the stock blazer valve and the K30 valve are identical on the out side, and I'm sure the K30 valve will bolt right in place of the stock one.

I have the K30 valve, but I want to get a new one

Anyone know were I can get a new one?
Can a brake proportioning valve be rebuilt?
Tried Summit, NAPA, Oreilly's, LMC with no luck.

Thank you
