I am gathering parts for a disc swap, I have a 68 power drum c20 set up now, switching to a 71-72 c20 power disc set up have a-arms, b-joints, spindles, rotors & caliprs, main link, still need to round up tie rod ends , master cylinder and prop valve. Where is the best place to get this stuff? Booster will still work right? Why are new prop valves so pricey? thanks

For about half the cost of a new prop valve you can get an adjustable one.

Why not use an existing prop. valve from the wrecker...Either that or get an adjustable like the man says...
Just don't give in and buy that "send the dealer on vacation again" prop valve..
Your $$$ is better spent on YOUR truck..
The only reason those things are so 'spensive is cause they know how badly you want one..
