Wushaw, do you know if it is gear driven, or a bolt on with belt drive? I would suggest trying NAPA first. P.A. Ross Machinery Co. handles Continental Red Seal engines, I'm sure they could hook you up. 4349 Cedar Lake Dr. 1-800-229-1546.. They are in the Dallas yellow pages, ad says "Serving I-30 @ Loop 12", so I guess they are near there.
Good luck....That's a "hard-to-find" item if there ever was one. The pump ISN'T part of the engine itself, but was a Massey item. (Made by vendor for Massey. Not sure who made that particular one. Maybe Cessna) Engine parts supplier MIGHT have access, but it won't be an actual "Continental" part/component. I'm talking with a salvage yard today about some other Massey items. I'll see what I can dig up on the 85 power steering pump (or rebuild kit) or change-over to another type of pump.
