The adapter for my AX-5 bell housing to an NP-435 got here today! The main shaft will have to come out of the NP to be shortened and then re-splined. I lucked out and snagged an NP that had a rebuild recently before going to the junkyard. I have a plan for a homespun crawl box. The crawl box will serve as the adapter for the Bronco Dana 20.
