Differential Dimensions?

Hi all,

I'm sick of shattering differentials in my E-Savage (the actual production one, not a GP->E conversion), so I'm trying to see if I can shoehorn some other production differential into the E's case. Some of the folks on E-Savage.com have used the pinions from the Maxx trucks, and drilled out the bevel gear and case to 6mm to support that. I tried it, but the hub on the main bevel gear shattered while I was drilling out the hole. In addition, I keep shattering the internal bevel gears inside the diff cup, so switching to the Maxx pinions won't really help me on that score.

The E-Savage differential is the same size as the MT2 differential, which is quite a bit smaller (depth wise) than the Maxx differentials. I'm hoping that people can chime in with the dimensions of their trucks' diffs; I need to know the diameter of the main bevel gear, the diameter of the diff cup, and the depth from bearing to bearing (outside to outside) to see if anything else will fit inside the E-Savage case.

If anybody is willing to help me with this, I would appreciate it. Trucks that have occurred to me as possible donors include the CRT.5, Lightning series, and 8ights... but I'm willing to hear (read?) anything you've got.

Thanks!
