Just a quick question. Could someone post a picture of the end of the Parking brake swingarm that goes through the rocker panel? My truck was in pieces when I got it and I am not sure how the pedal is held in place. Is the arm supposed to have a cotter key and flat washer holding it in place? My swing arm doesn't have a hole in the end of the shaft and it is worn on the end.The truck is a 51 3100. Any help is appreiated. Thanks in advance.
