I think your actuating rod pivot link needs to be flipped 180 degrees and mounted so the threaded stud goes through the pedal hole pointing towards the center of the truck (securing nut should be on the inside of the pedal arm instead of the outside).
That will change the rod position to a better parallel alignment and make your setup operate better.
The pic from the '55.2 series Shop manual attached below doesn't really show it but the pivot attaching nut should be on the inner side of the pedal mounting hole.
