I was told the cab and all of it's components are the same as the 1/2 ton. Is that the case? Is that bumper and headlights the same? The grill? I would need a few teeth for my 1/2 ton grill and a bumper. I don't believe I would need much if anything from the cab and components, but will gather all that is needed if I can. It does have the motor and tranny in it. Would they be the same as used in the 1/2 ton?
