I have been reading other current threads on the AA adapter SM420 to Dana 18. I notice that they seem to be having problems with the location of the stock t-case and using spacers to lower it into position. Is this the case with Novak as well or just a AA problem. I already figured that the crossmember would have to be moved back due to increased length but dropped too?? Also, is the T-Case going to be moved left or right on that stock crossmember?? I didn't want to hijack that other thread with these questions so I figured I would start a new one.
