Professor 229 might be referring to 6.00x16" 6-lug rims used on 1/2 ton GMC New Design trucks?

Tim got it right..... I am not sure of my profile and the 47 listed and I should change that. The '47 was sold along with the 1945 GMC.... which had the rims I needed. The new project is a long story and there is no way it is going to be put back stock. It is a 1928 Chevy and I am putting a 1950 Chevy donor frame under it to get modern everything, but will need some narrow rims... It is a three to four year project although it is moving along better than I thought. I have a set of wide turbine rims that are beautiful for the truck but they are REALLY wide and I thought about customizing the fenders as well, but like I said, I am in no hurry and will hit the swap meets. I remember split rims in the old days and when we mounted them and inflated them, I remember the mechanics placing the rims under the hoist and lowering the hoist so if the rims cam apart violently, nobody would be hurt. I passed on the rims, by the way. The ad I placed on CL said I needed four and assumed he had four. He had two....

Thanks to everyone for the advice.. I will keep looking.
