Also check for bottle cage mounts on the underside of the downtube. In the earlier models even the racing frames had them.
There were no early racing bikes. It was the Sport Touring bike in '83, and just the ST and a mountain bike in '84. The racing bikes don't show up until 1985. Unless you meant those.
