This is the 1966 to 1976 GM Saginaw style pump. But it will mount to most Chevy/GM engines with the correct mounting bracket. This pump uses the 5/8 keyed shaft for the pulley.
This has a beautiful chromed finish. It includes the nut to hold the pulley on the shaft, but does not include the pulley. Note: If using on 1974 and later you will need to make a custom hose. To go from 5/8 inverted flare to metric o-ring.
