1972 c20 master cylinder - no match

[rx78nt1alex]

So after much research for swapping in a 1972 C-20 3/4 ton brake master cylinder and booster for my 1971 C-10 1/2 ton brake master cylinder and booster, I finally found the sizes and part numbers for making your own lines to connect the master cylinder to the proportioning valve that are crossed as per the factory diagram for C-20/C-30. (Picture 1)

The front most port on a factory booster (part number 50-1007 from Oreilly, with correct large reservoir in rear and small in front) is as follows if pictured by standing on the driver's side fender staring across at the side of the master cylinder (Picture 2)

Picture 3 shows what the part numbers are and the fitting size.

As a side note, NAPA sells an 1/4" x 8" line with the 9/16"-18 blue fitting x 7/16"-24 for about $5.49 each. The green fittings are $3.15 for 5 (5 in one box). I bought a 40" length of 3/16" tubing with other fittings for about $6.70 (I can cut it and flare it with the correct fittings later).

How you bend it is up to you. I'm going to take advantage of the perk of how my employer also owns Ridgid tools and get the benders at discount.
