Checking on replacing my 6 ports on my 1984 Hunter 31. Looking at both Bomar/Gray and Beckson. What confuses me is the both have a 2" spigot, and they say to trim it down to fit even with the trim ring . Has anyone really done this,or just let it stay the way it is. My ports measure 1 1/2" and stick out about 1/2" from the trim ring.ThanksDennis Duncan
