    so try to fit a one pieces on a 2 pieces frame is not easy....you can do it but is not a direct retro fit...you have to glue the portion where the 2 pieces have tabs to hold it in place!

    the pros on the retro fit one pieces rubber kit is the rubber is not the same outside as the 2 pieces, youv got a exterior seal fitement that is way better than a 2 pieces! hope that post help some one like me to learn this concept! :)

    I'd guess that the biggest difference is the fit at the top. The 70's vent glass comes up to a higher point than the 80's vent glass.
