Hello everyone i own a 1986 f250 4x4 6.9 idi c6 trans not sure on transfer case or axle ratio. Looks like a dana 50 hd ttb in front and dana 60 rear? Anyways its a super cab long bed. I have a 12v 6bt p pumped and alission trans 6 spd 4x4 trans and transfer case wiring harness(whole donor truck). The 6.9 idi is wore out. So i want to swap keep it all mechanical thinking of a manual trans 6bt set up. Where to start what is needed were recomended parts such as swap plates could i reuse the c6 behind the cummings?? Is it a bolt in??
