On the subject of exhaust pipe clearance, on my '41 Plymouth woodie, in order to provide enough room under the car where the exhaust pipe goes over the rear axle, the manufacturer of the wooden body just cut a square hole in the rear wood floor to give an additional 3/4" of space and then nailed down a piece of sheetmatel to cover the hole. I had three '41 Plymouth woodie parts cars and they all had the same "hi-tech" solution to the clearance problem.
