1973-1993 will cover what you need. You may have to use 1980 seat mounts for the 1992 seat (this is just an example) or something on that order but those years will pretty much interchange. If I remember correctly 1980 or '81 was the last year for the '70's style dash and the following year they changed to the newer style (check out an '85 model). Dash wiring may be a little different but it all interchanges pretty easily.
