Hello from JA My name is Woody. I will be glad to assist you today. I have been servicing ALL Major Brands of Appliances for 33 Years, and have over 100,000 in home repairs and over 50,000 phone and internet repairs under my belt. I`m sorry to say but you will not find parts for that old of a unit .
By law the manufactures only have to keep appliance replacement parts in stock for 7 years after the appliance was discontinued.
Your best bet would possibly antique stores , or ebay to get another one for parts
