I've been running the cen ring and pinion on the XL alum cup and gears. http://www.rc-monster.com/forum/showthread.php?t=21219
The only problem so far was my screws backing out of the cup and breaking off. I need to get a new cup, I've been using a plastic diff cup from one of my rcs so I could get my Savage fix. A little more time to let the loc-tite set probably would have helped. Sound like the new HPI cup are a reasonable price and nothing to mod either.

How close was the fit? They seemed just a bit off when I modded mine, but don't recall exactly. If I could put the hpi R&P on the Cen diff I would (assuming I break mine anytime soon)
