Anybody know if July was the last month for convertible production in 63?
Yes, the 1965 production went into the 1st week of August. Even though the start/end of production moved around a lot, production going into August is late. For instance, 1964 production ended the 1st week of July. Some years were even late June.My '65 HT cowl tag has 07E on it which is 07 = July E = Fifth Week 18476. Since the
numbers started at 10001 then this means my car was the 8476th produced to that date.
I know for a fact that the '65 models came to our dealership in late August '64 because
that was when I bought my original '65 SS. Don't know about Convertibles but most likely
they quit becoming available along with the other model Novas at the August cutoff date.
As Bod wrote, probably the same as the later '65 models.
