I would recomend a 1967 ford shop manual, It covers far more than a chiltons. You can get a reproduction shop manual from most any Cougar or Mustang vender. they are more expensive but more than worth it. Unless Chiltons has up dated the one they have sence I got one, You will not be happy with it. No vacume headlight info and no turn signel info as the most important missing from chiltons Neal.
