Thanks BarneyS!
I reviewed your thread and
Climbon's thread extensively while looking at the hitch figuring out how everything worked. It is actually incredibly simple once you can put your hands on one!
I'm going to call Hensley tomorrow and try and get the new spring bar bushing. Did you replace yours and if so do you recall how much it was?
I thought long and hard about a complete dis assembly to do exactly as you did, but once I saw the bearings looked to be in good shape I really couldn't justify it.
I got super lucky on the frame brackets. I had no idea when I picked it up that I was getting both types of frame brackets.
