Steve, here's a couple of pics to help you locate the frame numbers tomorrow. The engine compartment location is the easiest to see/find. The location under the cab will need a mirror and flashlight to see with the cab on. Both locations have the same partial VIN stamp. A 1972 Chevy St.Louis truck will definitely have the frame stamped with the partial VIN. The partial VIN should be 2S120172, (if the cab VIN matches the reproduced SPID VIN). Check that against the cab VIN plate. And check the cab VIN plate for the correct rosette rivets. Partial VIN's are the last 8 digits of the whole VIN.
