Bill-----How are you determining the year by subtle clues ? I'm guessing you're looking at the front turn signals that are larger [than the common Signal Stat] with a bastardized 3 screw mounting for the lens . I have a EM 5500 that has those lenses that I couldn't identify to replace . Then the first year or so, were the turn signals all up on the cowl between door and hood ? My EM 5500 also has front parking lights mounted behind the grille . Then somewhere along the way, GM started using the plastic square signal lights with single contact bulbs for the turn signal and a marker light visable only from the side . I thought that light should have had a double contact bulb for parking light as well .
