[442w30]

Going by my experience with other brands, as well as brands that have more definitive documentation in regards to production figures, I don't think you can use a general percentage on a ragtop. I believe ragtops (and Elkys, too!) carry different weight. For example, it's not unusual for ragtops to have a higher percentage of AC installations than hardtops. While this would be contrary to logic (as one can lower the top for free AC!), there's also the factor that a ragtop buyer may have been more upwardly mobile and in a different life place than the typical hardtop buyer. We can assume people didn't want to go fast in a ragtop and would settle for a regular 396 or maybe there's a guy out there who wanted the best of everything. There's just no way to estimate. If you don't believe me, check out production figures of 442 sport coupes with the W-30 package versus ragtops. I think you'll be surprised on the skew.
