That is the trim tag location, however that is not a trim tag from a domestic 67 (just looks like a piece of metal punched with the some numbers, 124377 is all I can see) Check this site for '67 trim tag pictures and hidden VIN #'s.
The car seems to be monkeyed with. Be carful before you lay out any money. and yes, '67 VIN's should be on the door jam. Any better pictures?
