Well, I just picked up the 1983 Supra Sport I bought off of ebay last week. Frame is really clean, paint is in good shape.
So far, it needs a replacement front brake (got one out of the parts bin), tires, tubes, seat (got several thrift store seats on hand), bar tape, bearings and cables. Surprised this model has steel handlebars. Too bad the bike is too small. It will end up on C/L.
Serial number is L996442. RD has a "ZD" (April 1983) code on it. Bike has Suntour AR derailleurs.
