How many different styles of xfer case flanges are there? I have three xfer cases (3speed) and all of them are different. I have a 63 Fj40 that I put 78 axles under, but the flange for the xfercase and axle pinion are different. None of the flanges on the 3 xfercases matches the rear or front pinion flange. I find this odd! Any suggestions???
