Would any production # gurus know how many '70 Cutlass Convertible 350-4spd cars may have been built? Don't have anymore info on this particular car yet, but will post when I get.....thanks in advance!

 

The only Cutlass convertible in '70 is the Cutlass Supreme convertible. Could be had with a 350 or a 455. Either available with the M-20 wide ratio or the M-21 close ratio 4-speed.
Unless someone has records obtained many years ago, here is the only records left: A breakdown of M-20s and M21s by series through June (missing July production.
Cutlass Supreme, all models (4200 series)
M-20 679 (probably ~ 735 total)
M-21 203 (probably ~ 220 total)
So probably less than 1,000 of the Cutlass Supremes with 4-apeeds

So it is anybody's guess from there, but it has to be a pretty small number of 350 Convertibles with 4-speed.

 

Thanks for the response wmachine! I'll be looking at the car this weekend. I'll post tag when I get it....
