Thanks, got some screws and small taps ordered.
Bit of trivia--- the difference between screws and bolts, screws are to be inserted into a object. Bolts are to be inserted through an object with a nut (fastener) attached.
Thought I would share, anyway some more track links. And I did have to change one op, I was planning on using a slitting saw to part the individual pads but my collet/saw did not have the clearance. So I had to make them a tad longer to allow the old human powered hack saw room for my perfectly straight hand cuts
