I have ground the threaded end of the KP bolt many times to get it to take hold. I also have 1/2" punch that is tapered so that I can line up the KP into the top plate. Also if this is an old Morgan the KP bolt will be 1/2 BSF If it is a late model Morgan I think it will be 1/2" SAE but check do not take My word for anything. I use a big rubber hammer to pound the spring into position/ I have used a long 3/8" bolt to get the KP lined up. I also used two long threaded rods to move the bottom of the KP into position. By tightening one and loosening the other I can tip the KP a bit. Lots of tricks including letting this job sit overnight and trying again the next day.
