Well... it took me longer than I thought as life got in the way (again!) but this little modification works great!
Used 3 or 4 bits (broke a couple) to get thru (no countersink) and went with a metric SS round headed bolt 6 x 20mm (just about 1/4'' x 3/4'') and a metric acorn nut #6, all from HD, $1.75 for both. Added some thread lock and voila!!
Thanks TennX and Hans&Feet for your input!!
