I am trying to get this stove working soon...and one of the things I have to do is replace the door gasket....its smashed flat...worn out...tattered...I am assuming all door gaskets start out round.....even though its hard to imagine this gasket having been round ever!...it looks like the typical rope type...and there is a hardware store here that sells the gasket with adhesive...but they have two different sizes...3/8" and 1/2" ..I guess my first question is are there any other sizes it could be?...like 5/8" or 3/4" because it looks big...but of course its smashed flat...so its hard to tell...to me it diffidently looks larger than 3/8" so if there are only two sizes commonly used...then its got to be 1/2"...but if there is such thing as 5/8" then I am not so sure....its an old stove so the brand will probably not help...but its a horizon eclipse.....any advice would help!..thanks
