Yeah 5,500 seems a bit... I dunno. Much for that rear diff kit.

I finally got around to pressing in the wheel bearings and flanges and sliding it together for the 1st time with all the parts. Everything fits and the axles are perfect. So all that is left is welding up the subframe for the mounts and bracing and then the driveshaft. I will wait till next spring for the driveshaft and the install because I am saving for my diesel project but I do not think there will be any problems with this at all. So in conclusion the clk63 BS wheel flanges{note the bolts are the larger 14mm instead of the 12mm} and stock bearing with a little machine work on the spindles to clear for the C63 axles are what is needed. The differential fits in the stock front mount location and one of the rear mounts is lined up properly but has to be clearanced and the other has to be made. I am going to box up the subframe after the mounts are welded in.
I did this on the standard subframe not the v8 ones. I am going to reinforce some other areas in the subframe also to make sure that I do not twist or break it. I have a 2800 stall converter for the 722.6 coming so I should be able to launch pretty hard. If not I will go bigger on the stall eventually.
