How many 73 Vert 4-speed produced??????
Can anyone here give me a specific number in regards to.... out of the 4,943 1973 verts produced.... how many 73 Convertble, 4-speeds were produced? I have tried to research this number and I get close but maybe someone here would have a more definitive answer for me.
Thanks in advance,

Nope, the detailed breakdown doesn't exist. The records from St. Louis were destroyed. The closest you can do is to use the black book or other sources to approximate the percentage of cars that were verts and 4 speeds and approximate the final number.

If.....and that's a big "IF"..... I have done my math correctly, I would approximate that at the most 500 Verts were 4-speed's. Depending on how you run the numbers....total number of Coupe's (25,521) vs Vert's (4,943) and the total number of 4-speed's (3,704) produced with 41.2% of all being 4-speed's......this end production number may be much lower. Maybe as low as 100.
GM made 5X's the amount of coupe's than they made Vert's this year......
Any math guru's here....because I surely am not? This would be a great math lesson for your child / student. So, unless proven otherwise....(math wise)....I think I am going with the 100 number.

3704 Corvettes in 1973 had the optional M-21 4-Speed Close Ratio Manual Transmission. 17,927 cars had the M40 Turbo Hydra-Matic Automatic Transmission (58.85%). The balance of the cars had the M20 wide ratio 4 speed manual.
If the OP has an M-21 close ratio, then we can say it is one of approximately 601 M-21 verts. Unfortunately, he did not specify if it was an M-20 or M-21. 8,833 Corvettes were made in 1973 with the M-20, which means there was a total of 12,537 Corvettes with a 4 speed transmission in 1973 which was 41.15% of the total. This means that we can estimate that 2,034 convertibles had 4 speed transmissions (601 M-21 and 1433 M-20).

Actually, this number is very wrong.

Thanks for all the input....I am sure someone else here will have another point of view...math wise.

Its a M-21....So, for all intents and purpose's...I will live with the 601 number. I put the calculator away....it was driving me zooey! But, you are thinking in the same train of thought I was....trying to guesstimate is just that...but, at least I have a good educated guesstiment.

About 40% of all 73's were 4 speeds. So 788 x 40% = 315.
Mine also has PO2 wheel covers, 6% of all production. So can I figure the 315 x 6%? That would be around 20 cars.
If 20 makes sense mine also has PS, PB, and AM FM Stereo.
So, can my car really be that rare? Doug
