Known trim tag date range runs from 02D to 03A (very few early cars for initial press release at proving grounds), and 03C to 04B. There are no known 03B cars.

There is old evidence of the Z16 convertible existing, from more than one source who did not know each other at the time, with exactly matching stories as to where it was sold new, who owned it first, and the colors. There were also two independent sources with matching stories of the car's demise in an accident. So I have no doubt it existed.

But Paul is correct that the ECL total for the Z16 option on 13867 [SS convertible] series cars is listed as 0 produced, while 201 is the total listed for the 13837 [SS coupe] series. (A production Z16 convertible would have its own ECL because an SS convertible already had a boxed frame while an SS coupe did not, which makes the parts content lists different for the two body styles.)

However, the ECL totals do not include COPO orders, or vehicles hand built at the Tech Center, so either of those could have been the origin of the Z16 convertible. And that seems likely since the interior and exterior colors were not from list of available colors for a "production" Z16.
