A couple of production documents that I've seen posted recently have me thinking about when the three speed manual was phased out of 1969 production.
Total three speed production would seem to be 252 units (taking all of the RPO transmission totals and subtracting it from the total number of Corvettes built in 1969 - not a perfect solution, but its what we have). A certain production record seems to indicate that 252 three speed manual cars were built by the end of September 1969. That means no three speed manual cars for at least the last three months of production.
We know that Chevrolet changed the main case and side cover for the four speed transmission in September/October 1969. We know that Cheverolet standardized the M-20 four speed manual transmission for the 1970 model year. Is it possible that they made the change to standardize the four speed at the normal model year break (September 1969).
What is the latest three speed manual transmission 1969 that we know of? Anybody have a verified VIN after car number 31000 or so? Is there any documentation out there that would indicate that the three speed was either available or discontinued at some point in late 1969?
