on a early 90's 28 portlight.They are Beckson,I know cutout size but I am not sure whether to order 1 inch or 2 inch spigot.If anyone has a 28 and has replaced their portlights,let me know please.Also,if you bought a different kind that went in with a minimum of cutting let me know.I would love to do stainless but I am not keen on the prices to do all 4.Thanks
