let me double check but I had the gasket replaced about 4 months ago and I don't remember it being there then either.
i found it! the problem is I can't get that whole door front off
Please let me know if you have additional questions or need clarification. There is no additional charge for any follow up help!
ok so one last thing- I hadn't taken the front clamp off and I can do that....so the rear clamp will go outside on top of the bellow, around the edge, and then I guess the bellow will fold back on itself there right? and then I pull the rest out to the front and redo the front clamp
