Thanks to Max for this piece of advise:
"One thing I learned from this very list is to sleep on a mistake and fix it the next day. Extremely valuable advice, seems always to work..."
The desire to get things done may be driving to ask questions sooner than I need to. If I get the time tonight then one of the (L) brackets for the front may need to be re-fabbed, due to the drilling. All the enlarging of holes happened to the bracket instead of the rib or spar.
