Well to be fair to me (my first concern) I did have a thread a couple months ago asking about the disc rebuild.
With the original trailing arms, I can see how that works and works very well. Being ridged now, so that I can lift them with the hitch, I may have to do something innovative to get that affect. I may look at adding a mushroom shaped extension to the draw bolt ends.
I'm also making an adapter tongue so I can pull them off a ball hitch.
