Thanks, the manual steering couplings that I have from my 65 and 66parts car are about 3 inches long (Without the cap) and the power steering one they sent is 3 and 5/8th inches long. From what you are saying it sounds like the correct one for my car should be the same length as the manual ones that I have. The wrecker I got it from does not have a shorter one. What I need is just the empty casing about 3 inches long that fits on the power steering box.
