I have a 91 Z28 convertible that is a 5 speed. I am trying to find how many were built. I know they made 3203 Z28 convertibles that year but have been unable to find how many were 5 speeds. I was told somewhere between 500-600 and I am trying to confirm this.

Using those two links and a little math you can come up with a good estimate, but as they said there doesn't seem to be an accurate number for individual options. To do so would require a database with rpo codes for every single vehicle.
