I'm trying to gather up parts for my rear end and have come across a few issues. I've found an early bronco rear end that is 53.5" flange to flange and also another housing that Im not sure what it came out of that is 52.75". Both are small bearing housings although one guy swears its a large bearing housing and I can clearly see in the picture that it is not. My problem is that I can get early bronco axles for dirt cheap but I'm not sure if they will fit the shorter housing. The shorter housing will put my width exactly where it needs to be and its a lot cheaper. I've never built a rear end before so does anyone know if axle length has to be exact or will the early bronco(1966-1977) axles fit either housing?
