ok starting the swap in of my 77 f150 HP 44 next week the axle is completly rebuilt and ready to go in my question is i have pro comp SS extended lines will they bolt up to the ford calipers? i really hated to trash em after only 6 months of use

not to sure but i think that the line bolt that attaches the brake line to the caliper is different diameter. tried to use a ford brake line on a tj for a trail fix and ran into that problem, bolt would not go through the ford brake line, but then again that was a stock line. just give it a shot you already have the lines, just check for leaks.
