Marc,

If you have GM production numbers by model in years other than 1951 and 1953, would be willing to share them?

I have only seen the model-production breakdown for two years: 1950 and 1953

The lowest production year for Advance -Design trucks was the partial-production year, 1947. 1952 was the lowest full-year production, about 40,000 total trucks less than in 1953.

The 47-55 production data at this link are not exactly the same as the GM data, perhaps because the GM data was by calendar year (tax year) and the other link might show production by model year?
