So my PA20 Parts Catalog (Univair part # 20PM) Figure 33 item 8 shows part number 40123-80 for 50, 51 and 52 Pacer. According to drawing 40123 in the SWPC Drawing CD the -80 cable is 77 1/8" long. The 1953 model PA20 uses a 40123-93 lower flap control cable that the drawing shows to be 84 1/16" long.
