Thanks, glad you enjoyed.Just read the whole thread, really great writeup and a nice job on everything. Only idea on your steering box problem would be to sacrifice an allen key and weld it into that. Then you'll have a nice post to get something real on.
Tossing up between welding on a nut or your suggestion of allen key. Same concept, I'll just see which I think is easier.
I now have a replacement on the way, so don't have to worry quite so much about keeping it serviceable.
