I would like to get the drawing identified in the title if possible. This part is simply the extension spring which returns the lever arm on the Goodyear Brake Assembly to the neutral position after heel brake pressure has been released. It is clearly identified in the 11AC Chief service manual and I think it is used on the Champ series as well. It is not available from the Museum and I have asked in the type club forums as well. Your assistance is appreciated.
