I bought this during my C3 SBC restoration. I was looking for a driver side, outboard alternator bracket that mounted to the head instead of the exhaust manifold or header. It did not work in my application since the bracket interfeers with the power steering pump.

This is a beautiful bracket if you don't have power steering.
Original cost $170.00, asking $135 shipped
