I had a '77 with the 400/203 that came that way from the factory.
VIN was on the door opening (cab) by the striker plate, IIRC.
If you get a cab from a salvage yard it will have a salvage title.
The factory pop-rivets are a star shape that differs from ordinary pop-rivets.
If you remove the VIN tag from the cab, say to repaint, you can take it to the State Patrol and if it matches the VIN stamped in the frame they will pop-rivet the VIN tag back on with the correct rivet but I don't think this will work with what your doing since they won't match. Officers nearly never check the VIN on the frame but if they do they need to match or you'll have a lot of explaining to do.
Bonded title is the best way to go to avoid potential hassles down the road, IMO.
