Don't be surprised if it takes 10-15 calls to finally get through. Ask for a "Restoration Package" (it's free in the USA). They will want your Vehicle Identification Number and year for your Vehicle. The restoration package they send includes complete engineering specifications for your year truck, and also a very long list of parts vendors for classic Chevrolet. The USA Restoration Pack will not give you specific information for your individual vehicle, but generic info for the model year of your Vintage Chevrolet.
For those of you in Canada, you should contact:
GM Canada Vintage Vehicle Services Phone: (in Canada) 1-888-467-6853, between 8:00 a.m. and 5:00 p.m. Eastern time. (Outside Canada 1-905-644-3387 or 1-905-644-4060).
Unlike the US Restoration Packs, GM Canada charges for theirs however, unlike the USA version, you will receive information specific to your particular vehicle.
The cost is as follows: For vehicles 1963 & older: $25.00 (CDN) + GST & PST (Ont.) for 1964 to current vehicles: $45.00 (CDN) + GST & PST (Ont.)
