Wheel Fitment Question

[focijoe]

I bought a set of wheels for my 04 Silverado 1500 4X4 a few years ago. When I tried to put them on the truck the center hole was too small to fit over the hubs on the truck. Only by a few millimeters. The bolt pattern was right just wouldn't fit over the hubs. I want to sell the wheels but I have no idea what vehicles they fit. Can't seem to find anything online. Heres the info on the wheels:

 

Brand: Weld Racing Evo 476 Velociti 6

Size: 16"X8"

Bolt Pattern: 6X5.5

Offset: 15mm

Backspace: 5.09"

Model No.: 476-68A883

 

Any idea what these would fit?

I measured the center bore of the wheels and it is 76.2mm. It looks like GM 1/2 ton trucks center bore is 78.3mm which would explain why they wouldn't fit. So there is a difference of 2.1mm. Could the wheel center bore be enlarged by a machine shop to 78.3mm? I cannot find a vehicle that has a 76.2mm center bore so i am really confused.
