That's a pretty big frame. Looks bigger than the Trek I had and mine was a 58 (I'm 6'1).
Any crank, derailleur and cassette? You may be limted depending on the 1983 spacing. If it's a 6 speed in the back, you may be limited to a 7 speed cassette. Not sure if it can be spread to an 8-10 speed without special attention.
