You are correct....there are 1000's of wheels made for our 6 lug trucks....unfortunatley, there are several STYLES of wheels that look VERY good that do not come in a center bore large enough to go on them. The 6 lug torq thrust style wheels offered by many companies is one of them. Go to any wheel site and find the center bore size for our trucks...I think its 4.25 and then look at all the 6 lug wheels that are 3.50, 3.75 and so on. There are a lot of threads on this site about miling them down. Summit, Coys, American Racing. I assure you there is also a thread on this site somewhere about swapping drums to car or van drums for a smaller center bore. I read it about a year ago. They may have been Pontiacdrums and bearings...I just cant remember. Hopefully some one will be able to find it.
