1991 GMC Jimmy VIN issue

[Memzd]

Hello everyone,
Got this strange issue with my 1991 GMC Jimmy VIN number. Windshield Plate and gloves box has this number:
1GKEV18KOMF517096
While on the frame under passenger this is it:
1GKEV18KOMF517095
Finally, registration document has this number:
GKE18KDMF517096

1- where are other hidden places to find VIN number in Jimmies?
2- is this normal to have two different numbers in one vehicle?

Thank you

[Keith Seymore]

1 - there are no other hidden VIN locations on a '91 Jimmy

2 - no it is not normal to have two VINs on the same vehicle (kinda frowned upon) but this looks like a mistake that was not caught.

Some discussion about the frame VINs, how they were done and how mistakes could be made:

With the advent of the internet, though, I've seen so many that there is no denying that mistakes got out.

From a previous thread:

The VIN stamper is a large hydraulic "press" hanging from a tool rail and with the weight offset by a "balancer" (imagine a Harley-Davidson hanging from the ceiling that you are supposed to maneuver into position and activate the turn signal). It is supposed to index to the next digit automatically -but - if you mis hit or get out of sequence for some reason then you have to make a repair. Chevy and GMC have different VIN sequence numbers, requiring different stampers hanging there, so if the operator grabs the wrong press and stamps a Chevy VIN on a GMC, for example, then not only is that particular truck wrong but you are out of sequence on every truck after that.

The assembly line repair person and/or the "quality man" (the foreman's right hand man) follow the vehicles down the line with an "X" stamp and a 5 lb hammer and correct the VIN sequence number as required.

Usually it's not just one truck. It normally takes several trucks before somebody notices, so you'll have five or six trucks that have to be fixed - all without the line stopping - it's quite a scramble for a few minutes while you figure out what went wrong and what has to happen to make it right. You pray nothing else goes to crap while you've got your two best guys otherwise unavailable.

In all that confusion it is easy to imagine how one truck every now and then could slip through.

So what you recommend or who to contact to rectify this since our Traffic department asking for a picture of original number on frame that matches dashboard plate and glove box VIN number.

Thank you
