Much more than 100. While it is not exact (cars did not come off the line in VIN sequence) my GTS has a sequential # in the 11,000's at the end of the second month of production.
100 383 cars? Probably less don't you think by an early october scheduled build? I was thinking 100 never mind trans! Heck they only produced 272 fastback 383s autos in 69 according to resources.
