I think this is from a 1950's Offy parts book. The facing page has printed instructions and the back of the page has a diagram showing how to set up the linkage on a 1949 to 1953 Ford or Merc's with a standard trans. The page is a little beat up, has small rip in the center. I'm asking $10 plus shipping. I accept Paypal, checks or postal money order's.
