Default Help with b44.?

Hey all.
I bought a b44.? From somebody at the track. It has ball differentials. The rear differential is slipping and I want to replace it. Does anybody know if a differential from a b 44.3 will fit?

Short answer is, yes, they use the same gearbox/case.

It's kinda ironic that the original B44 ball differential as an optional part for the B44.3. With that said, yes, you can buy a complete gear diff #9948. I'm pretty sure you will also need to change the input pinion gear and input shaft. Grab the B44.3 manual to get part numbers.

Thanks!
That is odd that the ball diff is an option.

My problem is that the track I race at is so slippery that I have to run a super loose rear diff setting. My ball diff is slipping very bad when I set it loose. I was hoping I could run a very thin oil in a gear diff to achieve what I'm trying for.
Any help is greatly appreciated.
