Refrigerator door seal replacement source

I have the standard Norcold on my 2005 2720. I discovered that the bottom of the door seal was bad and needed replacement.

My question is other than replacing the whole door has anyone found a source for the seal. I called Norcold and they only sell complete doors.

I looked at stick on foam seals but would like to go original equipment.

I am still looking for a replacement seal for my Norcold refrigerator or an inexpensive door with seal, Thanks, Summers Coming!!!
