Black rubber gasket for Thermador oven Model No. WO-16-A

Does anyone have or know someone who has a spare black rubber gasket for my Thermador electric oven, Model No. WO-16-A? It's the gasket that completely surrounds the oven and makes a seal between the oven and the wall that the oven is built into. Having a hard time finding one and I really need it! I have some spare parts for the matching Thermador 36" electric range I would be willing to trade for the gasket. [/b]
