Guessing the double bearing 2.0 center diff didn't help performance enough to justify keeping (or even holding onto for however many months it took till the EB48 2.0 came out)? I have both EB and NB 2.0's, and I wish all 3 diffs had double bearings, simply for the fact that when a diff bearing goes bad, I don't have to disassemble the diff and get at the fluid level just to swap out the diff big bearings. Also, I like the active toe out "C" option on the rear, but that function was removed for the 2.1. I do like that C-block having 2 screws directly to the chassis, especially since my 2.0's C-block has had a tendency to come loose for some reason (the forward 2 screws that hold it to the gearbox). I think I've got that fixed now by using flat head screws with CSK washer plus CA glue on the screw threads. Perhaps I could just drill and countersink some holes in the chassis to adapt that 2.1 C-block?
