Inquiry (采购产品): Old part number Ladies & gentlemen, I am rebuilding an aircrat and have a callout for a "3645 seal" by Chicago Gasket Co. The call out is from a parts sheet last updated about 1978. Can you help me locate this part, or provide an updated part number if there is one? The part is used in sealing the butterfly shaft on a carburetor. Thanks much. **** Hidden Message ***** George Dorris 83615 Company: G&S Aviation E-mail: gsaviate@citlink.net **** Hidden Message ***** gsaviate@citlink.net
