master cylinders

[old timer]

I am gathering parts to put the disc brakes on my pickup this winter.
I think I have everything needed except for the master cylinder.
The axles, rotors, and most parts are '75. When I looked up masters there are three different ones listed for non-power brakes.
1974, 1975 and 1976 to 1979 each have their own part number.
Can anyone steer me straight? Thanks The Minnesota Old Timer

Sorry I don't have an answer. I do know that the lines come out on the opposite side for the '73+ pickups. Also some had different size fittings but don't know their applications. I would think any mc for non-power discs with a 1.00" bore should work.

There's another thing to watch for. Starting in '73, the F100 (and later F150) had a lower brake pedal. Don't know how that will affect backfitting it to your truck but check it out, you might need the later brake pedal?
