I finally am officially working on the 51 Commander to get it to driver stage and work on it as I drive her. May have found the problem with the transmission. I was getting ready to adjust the throttle control linkage(0312-40, 0312-41) underneath and found it to be missing(pg 180, 51-54 Chassis parts catalog) So does anyone have the linkage, ball joint, and connectors for this? The previous owner put a large bolt through the brace to hold things together.
