60 60 60 is all i can say! Even though the 9 inch is good and strong { we have used one in a 2200 hp small block car } i put a 60 in my cj7 as havent looked back ! If your concern is the lug pattern cut off the ends and install ford big bearing ends and get axles from some one like moser as i did! You can then use the big bronco drum brakes. 60s hang down a little lower then the 9 inch but you wont have such an extreme drive shaft angle !60 60 60
