Ordered a bunch of gaskets from Woodstock, to my relief, much of the old gaskets were cemented only at the connection ends from the factory. On the door gasket the replacement was black - is this for aesthetics? - and the replacement had an additional 8 inch flat gasket with a sticky back. I called Woodstock and they had no instructions as to where it goes. But they were going to send me a pic, which hasn't happened yet. Just thought I'd ask here for those who may have run into this.
