I need to find my vin or a way to get my VIN. It is a 76 peterbilt, made 9-23-76 and I found a number on the crossmember that supports the rear of the cab and it is 01 36984M000 but I was told thats the Chassis ID number. Its not in the door jamb and I can absolutely not find it and cannot register it because of this. Where else do I look? Any help is appreciated.
