Wheels on a 70 GMC 1/2 ton - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone know what size wheel lug pattern is on the 70 GMC 6 lug??? Truck is 1/2 ton swb step. Also, can the rear axles be changed to a 5-lug pattern without changing the whole rear unit?

Jason is looking, pricing, ect for new wheels, and we know we're going to upgrade to disc brakes in the front. What we dont know is whether to stay with the 6-lug on the disc conversion, or go ahead and switch everything to 5-lug. Which is the most efficient?

Seems just doing the 6-lug conversion would be more simple, but
we'd both appreciate your help and comments, and wanna say THANKS in advance.
