brake master/prop valve swap

[Jon Scully]

Hello there,

I think there may be a good thread on here already (no luck with the searches-- search function could use some help on this site lol

----I have a 1971 blazer and would like to swap to a newer style master cylinder/prop valve system.

The main reason for the swap is the price of repo parts (my prop valve has a very slow 'sweat' from the bottom pin valve)-- If I can get parts to be safe and workable from a 73-87, that would be fine....Is this possible (edit-- by possibel, I mean with minimal fab and low price tag lol)?

Thanks for any and all advice,

Jon
