1967 GMC WS SB incorrect production #s

[arcticman]

I would like to start by saying that my opinions are just that. Early this year I purchased a very original 1 owner 67 K1500 WS SB and so I'm fairly new to this forum/site.

I was looking for information on 1967 GMC production #. I now know those #are not available, through the information I received on this site.
Because this information is not available the 1967 Chevrolet production #s are being used as a way to estimate GMC production#s by assuming that Chevrolet outsold GMC by 3 or 4 to 1.

I believe this estimate is not accurate and in fact, the correct #s may be less than 2 to 1.

When I posted pictures of my truck several months ago one member posted some pictures of his 67 k1500 sb and his vin # indicated his truck was 580. his last 4 # in his vin are 1580. mine are 1117.
