It is a 52 and where the rod that runs through the left side cab support to the back of the truck for the e-brake and is connected to the pivot for the pedal with a 1/4" or so pin. It is rusted into the mount on the rod and has so far resisted all of my efforts to get it out. It is just one of those things that you don't plan for. I will get it out but it is going to take more work than I wanted to have to do. The problem is that until it turns loose I can't get the remaining part of the e-brake out. That means that I can't move the pedal over far enough to get the rocker panel out to replace it.
