All of the '71-'75 Sports Tourers I've seen have exactly the same dropouts with the same notches, and most '76-'78 Superiors were created from leftover Sports Tourer frames.

The '62-'63 and '76-'78 Superiors came with a chainstay bridge instead of the built-in kickstand mount. Most had a standard round bridge while some of the late '70s models had a flat bridge that could be used to mount a bolt-on kickstand. A Superior with a built-in kickstand is called a '68 S/S Tourer or a '71-'75 Sports Tourer.
