have fun changing out the diff fluid after that guard gets welded on there. :-/

The pic above looks like R-R might have re-designed their diff guard.

A few yrs ago, Jack showed up in Moab with one on his VX. We had to do "mini grinder surgery" in the stoop parking lot to access the fill plug...
Dunno if his was welded on too high, or if they re-designed to allow access, but at the time, it looked beefy, but not well thought out...
