I bought '07 Super Duty Lariat take-off wheels, just for the tires, and for grins tried puttin em on before spooning off the rubber. Went on fine in the rear but there were clearance issues in the front. Would need the backspacers for sure.
I had already bought Am. Racing wheels for the rubber, so I have the '07OEM wheels with center caps for 4X4 laying here in the garage all boxed up. If anyone's interested just PM me....
