should be. body/sheet metal is pretty much 'interchangeable' from 1972 - 1993 dodge trucks. meaning for the most part, the sheet metal mounting points never changed. sure the body lines might not line up between pre 81 and post 81 but they will mount and function. the 1979 hood and cowl were used through 1993. the same club cab model cab was used through the entire run to the bitter end. The rear bed/box mounting point did change but marginally. I have a 78 rear bed on a 92 frame with only minor mods. as well, as 73 fenders, hood, doors on a 92 cab. Tailgates and doors did have a change in latch design and mounting points in later years.
