Eaton m90 supercharger crankshaft pulley from a 1989 Supercoupe. This came from a very low mileage car that was owned by a ford mechanic. The motor had some low end issues while still under it’s original warranty so when ford sent them the new motor he kept all the useable parts off the original engine and kept this in storage for the last 30 plus years . Very nice condition as seen in the pictures still retaining the majority of the original coating
