Well, the gasket isn't that expensive so it's probably worth taking a roll of the dice. I'd go with the self stick kind in this situation so you could rip it off it just didn't work out. I tried using a rope style gasket on my offset once and found out the hard way that my door would not close afterwards. Getting some gasket around the WSM door would probably be most helpful. I put the gasket on the door itself for a cleaner looking install.
