I shoot A/C/C 3-60s and I just heat up the uni bushing and pull it out. Then I take a 32 caliber bore brush and attach it to a cordless drill to clean out the glue and slightly rough up the inside of the shaft. Then a standard super nock wil fit. Some will be tight and you may have to lightly sand them but they will fit in a 3-60. I have some lumenoks on order to put in mine as we speak. I'm not sure if this will work on the other sizes.
