got 5 lugs now need brakes????

I used the lines, master cylinder, prop valve, hoses, everything from my 80 model donor. The lines fit perfectly into the older truck. The master cylinder bolted directly to the firewall, even the two large holes for the front brake hoses were already in the frame rails.

I installed it all into place then drill two 5/16 holes to bolt the prop valve to the front most crossmember. What you are seeing here are all unmodified 80 model lines. When you bolt all the lines in place, the prop valve will be resting snug against the front most corssmember beneath the radiator. Just drill two holes and bolt it to the crossmember.



I even used late model 3/16 brake line from the donor back to the rear of the truck and used a 73-87 rear hose too.
