I have a '66 Chevy K20 and I want to make it a dually. Will the factory wheels from a '66 Chevy C30 bolt onto a '66 Chevy K20. Both have eight lug hubs, however I do not know the lug spacing of each. The K20 has a flat bed, so clearance will not be an issue on the rear. Thanks in advance for the input.
