For clarification, if you meant doubling up on the gasket in the way of putting two gaskets on I didn't do that (would fear the same result of wearing two condoms). Its just The old one didn't have any cracks or tears, plus it wouldn't budge when I tried to pull it/pry it off. I just left it there and re-fastened the adaptor pan.

I must say, I was scared that putting the gasket on the main pan looked like it was going to be a pain to line up that many holes with so many screws. I was relieved to find that the gasket actually holds the screws in place making it super easy to just ratchet them all on.
