Hub size difference? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 72 chevy K 20 with 8 hole rims and a 4 1/2" center hole. I also have K 20 chassis (un sure of year) under a 71 GMC body it has 8 hole rims with a 4 3/4" center hole. Why the difference? The chevy has a corperate rear axle and the gmc a dana, but the front hubs are different too. Could this be clue to what year my chassis is? I know this is the place to ask to get it strait, the knowledge on this board is incredible.
