Wheel Question.

[dtkarst]

After finally getting things working the way I would like them to on my 66, i took it out for a spin, came back and sure enough the 15 year old dry rotted tires finally had enough and 3 of 4 were blasting air out the side walls. I have some tires from our SUV that had 16 inch tires on it since the rims are 16 on this. But I also found a set of rims from a 2001 Silverado that are 16'' and 6 lug, so my question is, will they bolt up or what modification would i need to make. Just curious.
