How to repair gasket around Electric Oven Door?

I have a 1986 White Westinghouse Electric Stove that was new when we bought our home. This is a self cleaning oven which I have never used because of lung problems.The seal that goes around the oven door is fraying in the back of the door and you can see mesh wiring. I can move the torn material over so far. Is there a repair kit to fix this. My stove is still in very good condition including the burner drip pans which still look like new. I do not want to buy another stove. This is a Harvest Gold Color. The Part Number is KF450GDH2.
