There's no readily available, precise production number for a Pontiac GTO with that specific combination of options (2006 model year, Quicksilver Metallic paint, manual transmission, black interior). GM doesn't typically release production figures broken down to that level of detail.
To find even an estimate, you would likely need to consult Pontiac GTO enthusiast forums or clubs, where members might have compiled some data through painstaking research of build sheets and other resources. Even then, a precise number is unlikely to be found.
