Canada GMC vin# help

[Curtis65]

What I believe to have is a 64gmc 3/4 4wd fleetside the problem is the vin in the door jam reads unlike any I've found on the several sites and forums. I think it's a Canadian gmc and being that I bought it in northern Canada what a great guess it is! I would like to be positive though.
Vin # reads...4K92504816967B.
Any help would be appreciated :





.....remember to check wind direction before peeing!!!
