I have the 9 in third member out of my Bronco ready for a rebuild, (serious slack in the gears!) I need to order a master overhaul kit but the parts guy wants to know if its a "2 pin" or a "4 pin" rear end. I don't have a clue and neither does he! Is he talking about the pins that hold the spider gears in place? help! Quail season starts this weekend! I want my Bronco running!
86 Bronco XLT - 351W H.O., C6 to NP208, Dana 44 front, 9 in rear 3.50 gears turnin' 32 x 11.50 tires, Nothing fancy, just a good ol' huntin' truck!
