Directive Systems has 50 insulators for $20.00 and 50 stainless keepers for
$30.00. Be careful that you get stainless if ordering from a nut and bolt
supplier. Mike

I looked for these for someone recently - but I did not try to order any.
M2 and Directive Systems would be the places I would try.
And you can also likely find them and places like McMaster Carr - I know they
sell the retaining hardware because I looked for someone Recently.
