Can I use a 4x4 master cylinder on a 2wd??

I just finished doing the brakes on my 1969 Ford F100, new shoes, hardware, and wheel cylinders. The pedal goes to the floor if you lightly put pressure on it, but if you firmly press it it stays put. I've bled the lines multiple times and it not externally leaking fluid. I was looking for master cylinder, its manual brakes. My buddy has a new master cylinder for a 4wd model, it looks EXACTLY the same. Would this work on my truck, not juts rigging it though?

If it's the same year and a manual M/C it will work. JMO
What year truck is the 4x4 i'm sure if it's close to your year and bolts on the same and has the same size bore it should work. Not sure about which years should work but i would say 67 thru 70 maybe 71 and 72 just not real sure on the year exchange. check the bore size and the depth and compare to your's. Why not just get a new one ? Brake systems are nothing to mess around with and do half arsh you know.

I know thats why I waned to know if it would work. The 4x4 is a 1969 like mine. This mc is brand new also not a reman so free would be a good deal to me. I didn't think there was a difference though.

Shouldn't be a problem if their the same like Cole says. I've put 2WD masters on my 4x4 with no problem. Make sure the brake line fittings are the same size
threads That go into the MC as the MC that they came out of. Also check that the plunger in the end that bolts up to the MC is the same depth.
