You could only get a convertible in a Cutlass S or 442 trim in 68 and they were very similar. The springs were different depending on engine type, towing package, etc. Get 442 springs they were the same whether convertible or Hardtop. Here's the page out of the assembly manual:

The "S" stands for S. There was no "Sport" model. It's just a name made up by the marketing department. There are no substantive mechanical differences between a Cutlass, Cutlass S, or Cutlass Supreme, just trim and base equipment differences.
