Where would I find the data plate on an early model 47 gmc Coe. Is the engine number in the same location on a gmc as a chevy on the distributor side of the engine. Need info for a bill of sale. Also truck has 5 bolt 20 inch wheels on it think it's a 1 1/2 ton has about a 11 ft wheel base. Was wondering what trucks might have interchangeable wheels with it. Have a scraper/ crusher business down the road thought I could maybe get them to set aside some good roller tires if I knew what might interchange wheel wise. It's hard to watch what goes through that place but can't save them all
