gasket

[WDG]

I'm not having any luck finding the inner door gasket for my WC 44SK.  Can anyone point me in the right direction?  I kept a sample piece of the old one but Fun Tronics and Soda Jerk Works don't seem to have it.  It's been a major hold up for me.  I've been looking at Mc Master Carr but not sure of getting the right one.  The old one is not reusable.  Any help  would be appreciated.
