Differential Removal 1981 300D

[mercedesny]

I need to change out the differential in my 1981 300D. I see 4 bolts on a rubber mount in the back (easy to get to) and 2 bolts in the front. I tried reaching over the driveshaft to get to these front bolts, but it seems too tight for a socket. Anybody removed one of these things? Would appreciate any tips you may have concerning wrench size, techniques, etc. Searched this forum but couldn't find anything specific. I'm using a rental car right now and need to get it changed soon. Thanks!
