Can anybody tell me what may be the latest build date for a 67 Coronet? I own a 67 500 2dr hardtop 383 4bbl dual exhaust car with a build date of June 26th(which was a Monday,the last week of production).I have never seen any 67 bbody of any type with a later build date,and I've been looking for 15 yrs. I have checked with Galen Govier and made other inquiries but nobody seems interested unless its a Hemi or a one of one car. Any help?
