GMC VINs always puzzle me, ha - but since you mentioned Bruceman's charts, now I'm really curious, because that's where I got my info - seems a 70 should start with C9E140? But clearly the VIN in the pic is Canadian and your decode makes sense - where did you find the Pennsylvania info, etc? I just thought GMC had to have a 9 in it as the 2nd digit for pre-72s?? Thanks.
