Parts inquiry. Enclosed is a picture of a 1927 JD engine. One can see a clip under the front RH nut of the front cylinder. i have been studying my various parts manuals and do not seem able to get my eyes on a picture of this part or a description of this part in the actual list of parts. i am wondering if anyone has a spare clip like this or has already made the m up and have a spare to sell. or have the dimensions of the clip. i'd rather find the actual clip or at least have it's dimensions before i would make one up. Your help is appreciated.
