Looks like no Braze-ons for the rear rack attachment for a 1983 Super Sport like my frame has so I will settle on calling my bike a 1983 Schwinn Voyageur (Frame build date)...put together in 1985 (head badge date) with 1981 Super Sport parts (crankset, hubs & rims, derailleurs, racks).
Here is the Tange Motocross decal on a 1983 Panasonic DX-4000 with a frame serial number 1 month later than mine:

So looks like another Tange Tubeset (stronger for touring?) was used in 1983.
Thanks for the help Forum.
