I broke one of mine last year and bought replacements at CW. Come in a 2 pack for about $6.00 so I have a spare for next time. I have seen the pics of Larry's design and it looks good as well. Might fab some like that but it is further down the mods list.
Still got a few moreof Paine's pointers higher up the list to do. Crossed a few more off the list this past winter.
