i have a chevy 3500 p/u in need of a body lift to accomadate 33x12.50 tires that rub a little. i cant seem to find the parts needed to give it the lift. can anyone point me in the right direction? i heard that o'reilly's in greensboro might have what i need but i dont know if i have to ask for another body style like the 1500. the truck is a 2000 model if this helps. i only need about 3 inches so i dont have to change anything. thanks for the info.
