I just brought a 1976 Chevy Stepside and I also have a 1980 Chevy in fair condition. The question is that can I use some of the those truck parts on my 76' Step? My 76' needs a dash board, instrument bezel, glove box, window regulator (both sides), brake booster, door panels, vent windows, door handels emergency brake handle. The 1980 has all these parts are they interchangeable?
