Don't think those have an aluminum housing. All are cast iron. Are you in need of a pump?
All that's left are Cardone remans. You can send your pump to Lee Steering in CA for a rebuild.
Jones and Turn One can sell you a new aluminum pump but they need a few parts out of your original. These parts are no longer made and allow the pump to work counterclockwise.
I've dealt with Lee and Turn One, both are great companies to do business with. Lee rebuilt a pump with AN fittings for $150.
Turn One built a new aluminum bodied pump with AN fittings for $350. Both dyno the pumps before they leave.
