Here's a site with Chevy production numbers for 1927-1957 and a link to a Chevy 1912-1931 site................... http://la.znet.com/~c1937/Prod.htm
1LowDelivery, Have you considered getting a "Resto-Pack" from Chevy? I used to work for them, and we would send these things out all the time (for free). I recently got one for my 51 pickup and they have gotten a little more cheesy over the years as they are now mostly photocopies. However, they usually include the production figures for your specific model (along with a bunch of other info you may or may not need). To get one, just call Chevrolet Cutomer****istance. If my memory serves me correctly, the number is 1-800-222-1020.
