ford 9"

Hello I'm looking for some advice. I have a 1979 f150 custom 4x4 with a 351m in it. It's completely stock nothing upgraded on it. I have had the idea of making it into a prerunner. I have decent skills for fabrication and a good shop to do so in but I just can't find the parts to build the...

There is a local offroad shop here that has a matching set of axles that came off a 79 bronco. There is the high pinont Dana 44 with radious arms and 4.10 gears and a 9" with 4.10s also. He is asking $500 for the set. Seemes like a good deal to me. What do you guys think?
