Alright guys, I found a 14bff. I will have to drive 40 minutes away to pick it up, but for $150 complete with wheels brakelines and all, I think it will be worth it. For starters, its off a 73-80 Chevy camper speacial 3/4 ton 2WD truck. Will this work on my 86' K5 Blazer?? What will I need to do to make this one work? The guy told me it had 4.56 gears with a detroit locker. Should I go for it???
