I have a GE ZISS480DRASS.  From what I can tell, this is the OEM replacement part, however, the dimensions were different than the seal I pulled out and it wouldn't work for my fridge as supplied.  I had to cut the part to get it to work.  Specifically, I had to cut 1 inch out of the middle between the two damper openings.  Overall it worked, but I'm not sure where the disconnect in the specifications is?
