Update: Did the basics. Fortuneatly the pin spanner tool still engaged in what remains of the butchered holes. Thankfully. It took some torque to rotate. Moved it below the horizontal plane and adjusted to suit. The set screws did not appear to have multiple "engagements" with the ALU body so I just adjusted, torqued with some extra and hope all works for the 50 mile ride in the AM. Seems my worries were just that.....but I will let you know after the ride!
