Brakes on 68 Differential and 72 Differential - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am sure this question has been asked before but I have not found an answer so here I go asking again. I have a 1968 6 lug that has new wheel cylinders and good brakes. I am getting ready to swap out to 72 front crossmember and 72 rear differential. I have found out something is different between the two rear ends but I am not sure what.

My questions are: Can I swap the 68 backing plates, wheel cylinders and shoes to the 72 rear end?? Can I buy 72 drums or redrill the lug holes on my 68 drums?? Thanks for your help in advance
