Power steering for postwar Mopar

[DonaldSmith]

I don't know if the Plymouth pitman arm is smaller than the Desoto  one.  They are different.  The DeSoto arm has vibration dampeners, while the Plymouth box has a dampener in the mount. 

See if the pitman arm will go on the shaft at all.  Mine was tight, and barely fit, with the nut just barely fully on.  But I marked them with white-out, and they haven't loosened up.  

I remember Cardone had a data sheet showing the pitman shaft diameter and number of splines of various gears.  That's how I found the model I bought.

Yeah, there is no way that the Plymouth Pitman arm will fit on the Cardone pitman shaft. Good idea looking for a Cardone data sheet. I will start there. Thanks very much!
