Nice job and pictorial layout Richard.
I particularly like how you secured the bolt heads with the wire like that. all of us suffer from constantly loosening bolts. I check my tractor using the quick "eyeball" method to see anything obvious. You'd be surprised how often I see a bolt making it's way loose. Of course one like yours would be hard to spot.
Rob-
Your post....post: "the older I get...the better I use to be.." Brings to mind something Jack Benny said one time.: "I'm not as good as I once was but I'm as good once as I ever was."
