Frequently they are missing. Some states went by engine number. | | | | | Joined: Sep 2001 Posts: 29,270 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,270 | | | | | | Joined: Apr 2001 Posts: 268 Shop Shark | | Shop Shark Joined: Apr 2001 Posts: 268 | Be aware in California trucks and some cars were resisted using the engine number, in which case if you swapped out a rebuilt engine you lost your S/N. And in other cases Ca used the vehicle Model and serial numbers stamped on the door plate and the frame.
I do not know about Chevys, but GMCs have the S/N stamped on the frame just in front of the passenger side front spring mount.
I do not know when this practice was started. But all my 3 GMCs and 1 Chevy have the S/N on the frame.
California was not consistent about how they registered this old trucks, it depended on the dealer and/or sales person and which DMV one went too.
It was a grab bag.
2 of my GMCs used the engine numbers and with no engines they were tough to get registered, the other one used the Door tag ID Model and S/N.
All are now registered using the Serial Plate I.D. Model and S/N.
What you might call the VIN...Vehicle Identification Number.
