Be sure and check the hardware that comes with the weights before you leave the dealer. For two weights, you get two long carriage bolts and two short ones, plus 4 nuts and washers per side. When I opened the box for my hardware, I was short two nuts and washers per side and had to arm-wrestle the parts guy to get them. Could have come up with them myself, but for the price, they need to give you all of them.
Incidentally, there were no mounting instructions with them. You use the two short bolts on the first weight and the long ones on the second. It's a little confusing because there are four holes in the wheel, but evidently you only use two bolts.
