Thanks for the clarification, the site I ended up to order the gaskets was very confusing.
I have a set of the rubber end pieces from the post 55 gasket set. Do you think I could use them on the 54 instead of the cork end pieces? I've had better luck in the past with the rubber over the cork. I understand that the side pieces are shaped different, but are the rubber ends usable.
Thanks for your help
