i have seen the 47-53 3800 trucks with the 8 lug dual wheels, does anyone know how wide the complete set up is from outside tire to outside tire, and would they be able to fit under a stock 3600 with a regular bed without having to widen the rear fenders? i have given some thought to putting these on if i could make them fit. i think it would be a neat look having a dually with a regular truck bed
