Info on 1967 GMC

[syncrov69]

I'd like to have many information on a 1967 models and resto tips. Are you able to decode this canadian truck VIN C9S1471102911? Why in any catalog the stepside rear fender are available for 68-72 truck but not for 67? What is the difference? If I Have found rust in the cab just over the windshield(water from the gutter,it is possible to repair it? If I change the cab and I like to keep the Vin number, where it's possible to found this rivet or it's regular rivet use to fix VIN plate?

Thank's for all your answer,

François
