Got the diff mount in today (yesterday, what day is it, lol!) and it looks like it will work fine with a few mods. Mugen diffs must be a weird size, as the 9.5 ofna diff is too long to fit, and the losi center diff I have is a bit short... I will be able to shim the bearings and take up the slack so no issue there. Just need to find some decent thickness 16x13 shims...
