You may need to replace the whole diff if you want the plastic spur. Correct me if I am wrong Jhautz, but the slipperential fits the 808, which also fits the losi. You could theoretically put the losi diff in the 808 and run the plastic spur.
Check out my custom converted 8ight:
Sub 7lb, lowest CG of any 1/8 buggy
Yea. Seems like that would work. You would need to change the bearings on the losi diff. It uses something out of the ordinary and the XB8 just uses normal 8x16x5 bearings. But it seems like that should work.
I can't decide if its more fun
to make it...
or break it...
