So far the only issue I see is that the new out drives are large enough to require some material to be removed from the diff case so that they don't rub or bind.

I will do a full photo layout and dimensional detail on this thread.

The biggest thing im concerned with is the rear left dogbone already bottoms out in the outdrive at full plunge (stock), so anything wider than 1mm may be an issue. Again, I dont have the car in front of me so im not sure how much material can be removed from the dogbone itself.

I am also planning to test fit a Caster S10B diff into the case. The ring gear is the same size so if the width fits It would be a good alternative. I have access to a pinion gear that uses a pin instead of the key but it will need to be shimmed to the shaft. I'll post photos if I get this to work. Caster Diff kits are $43 and the SC104x4 bearings are $7.29 a pair. So for about $100 for a set of Gear Diffs.

Im running on a outdoor medium bite track and it is loose in the rear end when getting back on power. Car is stock minus the j concepts steering rack and im running the center hole. The car just turns in very hard making it loose. My mid motor serpent is easier to drive and has more rear traction for example.
