I am rebuilding a 46 Chev 1/2 ton. Presently I have the GM rallye wheels off my 86 4x4 that I once owned. With 235/75 tires they rub when I turn left by the control arm/gear box. I bought some 2007 wheels off of kijiji and they had the total wrong offset. My question is I am going to order a new set of after market rims but don't know what to look at for offset. None of the charts go back to 46, and I hate to pay shipping and find out they aren't right. Anyone have experience on what will fit for tires and offset?
