1971 cutlass S 4spd convert

[442w30]

To clarify, it's a Cutlass Supreme, not a Cutlass S.

I have production numbers of 4-speeds from the GM Heritage Center, but for all CSs and not just the ragtop. All of them were 350s - no 455s had the 4-speed:

The CS is the 4200 series, right? So that would be 692 M20 cars built.

The Cutlass SX was auto-only, so is a 350 4-speed more interesting than a 455 auto? The former is prob rarer than the latter, which is already rare. Certainly a good find!
