The correct PN is "Dorman HELP! 31000 Power Steering Coupling Disc" found at just about any Advance Auto store. I listed it in my Hydroboost conversion here: http://forums.amceaglesden.com/index.php?topic=43869.msg341786#msg341786
This is an old thread, but there just isn't any information out there for our Eagles (or AMC's in general for that matter...)
I purchased this Dorman 31000 Rag Joint rebuild kit from my local O'Reillys and it was INCORRECT for my 1983 Eagle Wagon. The bolt holes on the steering coupling from the Eagle are 2-7/16" apart, and the bolt holes on the Dorman 31000 are 2-1/4" apart...Which is too short.
I have measured multiple steering column rag joints and shaft couplings that I have lying around my garage...they all measure 2-7/16" apart for the bolt holes, center to center.
I have been doing a TON of research on this, and have found what I thought to be the correct replacement...but it says the bolt holes are 2-9/16" apart...and yet some people have said it worked for them with their AMC! This part is the Lares 200 Rag Joint.
Then there is the 1970-82 Corvette Rag Joint. Found some measurement information, and it too comes in at 2-9/16" measurement center to center for the bolt holes.
So what is the correct rag joint??? What really is the correct measurement? Do I have oddball steering columns???
