I'm not really sure if this is the right place to post this, but I'll ask anyway. I have a fully built FJ80 front axle on the 40 that I am building. I just got finished fabbing a 3-link for the front, but I'm thinking that I am going to have clearance issues with the high pinion of the 80 axle. I never thought that I would say that, but I managed to get the frame low enough, and the axle high enough, that it is a problem with the caster correctly set. Are there any 8" low pinion diffs that would fit into the 80 housing and work?
