The last 'vert VIN on the 1969 Camaro Orphans list is 124679N701420 but another ~10,000 Camaros were produced after that. For the '69 MY, convertibles accounted for just under 8% of total Camaro production, so even assuming 'vert production peaked in advance of the warmer months, surely at least a few hundred more would've been made beyond that VIN?
