Hey guys i got a a LSPV from a 1980 pickup thinking it would be the same as one on a 1979. Well the one i got has an extra brake fitting yet the one that was on my truck has only two!
Is there any way i can use this without spending any extra money?
If not im just going to eliminate the valve and just run some rubber brake line and connect the two lines.
Nope. You gotta spend money. I would not advise connecting the two lines, cause unless you know, don't mess with your brakes. On the three line one, there is some return to your front.
My advice is just get a prop valve and put it inline on the 79, adjust it manually. Whats $30, compared to your life.
