welcome to the garage sinefire, there's lots of Canucks here, one will have the model ID - I'm not sure on that part, it's definitely a big bolt, over 1T, and I think "cab and chassis" from the factory .... the first number of the vin indicates it's a '56, or at least the tag is from a '56 .... if it has the single headlights it's 55-7. 58 & 9 have dual headlights
