Ford big bearing 9" with Detroit and alloy 31 spline axles in rear, and Dana 44 front with air locker and 30 spline alloy axles. Rear is one of the last Wild Horses super heavy duty housings. Similar setup on my '76 has proven to be bullet proof so far.
Don't know how many more pages it's going to take to finish it, but hopefully won't be 16.
Next week starts the wiring for the engine. Should be interesting cramming all those wires, relays, etc. into the small area of the Bronco, but Thomas says he can do it. They are up at the Fall Crawl in Harlan, Kentucky this weekend, so maybe a little R&R will help him focus next week.
