65 valiant steering coupler for power steering.

I don't know the exact year that box coupling changed but it did change. Applies to both manual and power steering applications. It got a little longer and the size of the blocks, spring clips, stuff inside changed also. You probably should provide pics, actual measurements, some more details to ensure you get the correct part. Good hunting
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.
