Lol Ben, I've been given a set, I bought a set out of a 77 Ford F-150 for 600.00 that needed to be totally rebuilt, they are in my Cherokee now. I would say now that I was ripped off. The last set I bought were 250.00 for the pair, bought from two diffrent people. The 44 was a drum break so I cut off the C's to convert over to disc, I also bought a 77 Chevy axle for 50.00 that I'm using the knuckels for and all the outter stuff, calipers, rotors and so on.
Its only what your willing to pay.
If use that front axle your going to need to run the Ford radius arms you know that right? Because 78 and 79 have cast on wedges. If you want to run some other form of control arm or adjustable long arm you will need a 1976, or 1977 F150 axle. Or later but you will have to convert to disc break.
Hope this helps
