I think I found a solution - and JRY above PM'd me confirming information. I saw the ones on 3-rivers - they are advertised for some kind of carbon arrows and made no mention of the uni bushings. On another vendor's website they had similar glue in adapters for Easton S-nock (uni-bushing). I ordered a couple doz. JRY PM'd me the size of the uni-bushing, and it looks like it is a match.
Too confusing. These are probably the same as 3-rivers has, but with the poor product description on the site it is not clear.
I'd think there would be a market for these - I'm sure I'm not the ONLY one that prefers the glue on nocks to uni-nocks....
thanks for the replies, guys!
