OK, scratch that part number lookup......was thinking Pantera. If you can give me an engine tag number, from the aluminum tag that was placed somewhere on the intake manifold, I may be able to walk backwards from the engine number on the tag, to the appropriate pulley number in the Ford Master Parts Catalog, of which I have a 1975 copy of the 65-72 parts as well as 73-79 or so version.
Let me know!
