Help with wheel terminology - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm looking at these for a '68 on a '72 chassis. It will be a short step with '72 cab, '68 front clip. With 5X5"BC discs front 5X5"BC drums rear. Stock suspension. The description says (offset is -11 and the Hub Bore is 78.3.) There is no information on backspacing. I assume the "hub bore" dimension is in millimeters???? I have no clue what "offset" means. The description specifically states that they fit '71 thru '98 Chevy pick up 2WD. What questions should I get answered before I buy?

These are 17" X 8"Wide. Comments please.
