I bought a 78 J-20 without a front axle. I found an axle that is supposed to fit. I don't have the ubolts though. It looks like one of the ubolts needs to be bigger than the rest of them because the spring pad is so close to the cast iron housing that the bolt has to go around that and it is bigger. Does that sound right? Also I need to get the piece that the ubolts go through and the nuts tighten against. I was thinking about using some flat bar and making them. Any ideas. I attached a pic.
