1966 production

Does anybody know what the last production date was for the 1966 Mustang model year? I own a 1966 convert. with a build date of July 14, 1966 Dearborn.  

I was at the factory back around then and as I remember the start and stop dates vary from year to year and plant to plant. Depending on what is involved in changeover to the new model year and availability and parts and sign off's and yadda yadda,,,, there was no set in stone date. Since the usual start date is the middle to end of Aug and since there was a new body for 67 I think yours is a pretty late because it took significant changeover to the new style. I have only seen reference to cars built in 66 as late as July but not an actual stop date. Maybe someone else knows when Dearborn stopped.
