Hello.Cruise-o-matic is the automatic transmission.The Sport Sprint option was a dress-up package consisting of a pin-stripe,chrome air cleaner,valve covers,and I think the chrome M/C cap.Hope that helps.
On a 67, pinstripes were not part of the package(66 only). IN 67 and 68, they were a separate option. The 67 sprint package consisted of a Tsignal hood, chrome aircleaner lid, vinyl covered shift handle, rocker panel mldgs, pop open gas cap. The trunk &1/4 panel trim was not part of the pkge. That also was separate in 67.
