An original Chevrolet page can feel like the end of a long search. There is the model number, there are the factory figures, and finally there is something more solid than another seller’s description.
Then you add the numbers.
A Stepside chart dated February 16, 1973 lists the eight-cylinder CC10903 with front and rear “model weights” of 2,615 and 1,682 pounds. The page defines model weight as curb weight plus an occupant allowance. A separate note adds a 150-pound minimum-payload allowance to the total.
That gives us 4,447 pounds. The printed total is 4,453. [1]
Six pounds is a small difference, but the page does not tell us which entry, if any, should change. Quietly replacing the total would hide the very thing another researcher might need to see.
We keep the printed figures, keep their footnotes and flag the discrepancy. If another original or a dated correction turns up, we can compare it without losing our starting point. The exact page, leaf date and model line belong with the citation.
This is an arithmetic puzzle in one document, not a measured truck weight or loading recommendation. “Model weight” is the source’s own term, and should not be substituted for other weight ratings. The inspected leaf does not establish the market.
