Guys I have a ? I just ordered a ball diff and need to know if the kit outdrive bearings on the gear diff are the same sized used on the ball diff and tranny case. I looked at my AE SC10 catalog and it says the diff outdrive bearings are 10x16mm and FT option for ball diff are 3/8x5/8. When I looked at the FT4.1 manual it says they are 10x16mm

Do I really need the t4 tranny cases? Is this all thats needed?
