Thanks E, I will put in a little more research time on this before starting. Was not aware fo the difference on the 240 and the 280 doors either, very good to know.
I will be working on the door seals for my '77' z next week and would be curious to see any pics of others work. I have the same situation, previous owner had lousy glue job and everything is falling off. I am considering McMaster Carr for doors, still not sure about rear hatch seals but open to any suggestions you might have.
