Hey man, before I was at the local track and all they had was MIP SC10 ball diffs with metric bearings( a local racer told me) which I figured would work out bc of what you said earler. The diff (MIP#9130) was EXACTLY the same as the AE diff I just put together (ASC#7678) and had the same EXACT problem as before, the outdrives are too short and the dog bones keep popping out. I threw my gear diff in it just so I could run a few laps.

So now I have nearly a hundred dollars worth of brand new, unusable diffs. Matt, do you think I could purchase just the outdrives from the 9853/SC10 kit and use my balls and hardware from the other kits ? I am getting frustrated with this situation and my gear diff blows which it makes it all worse, I spin out if I give anything more then 1/8th throttle exiting a turn. Thanks for all your help and sorry to be annoying man, no one else has any idea wtf im talking about.
