Outer Limits 4x4 Board

Ok so now i've moved my diff forward an inch by redrilling the sring perch. Im going to be making an extension up for the driveshaft. Should i put the new plate at the diff end or the transfer case end? or a half inch extension on either end? any difference?

either 1in at the t/case end or 1/2 either end wont matter

ohh ok good i didnt think there was much to worry about with the angles.
Cheers
