I just bought a single cab Chevy sport side truck, its an older model, but i really like that style. Its a 96. The guy i bought i from put aftermarket wheel on it. They are old and not to my liking. I've looked into the factory Z71 wheels on ebay, but it seems those are 6 lug rims, while the truck is 5. My question is is there an converter i could buy to convert it over to a 6 lug? would this be cost effective? thanks in adavance.
