inside frame is basic port
The outside part is the trim ring - unless you mean only the lens. Replacement lenses are available. Otherwise the port needs to go. (Or you could build up the broken part out of epoxy...) Replacing the ports is not bad. I replaced 6 on my '79 37 cutter last month. The only problem is that the drains have moved - so you need to fill in the old drain cut-out and cut-out new cut-outs. Not hard, but I went slow and so had to do a couple of passes at the cut-outs. Filling in is easy - use masking tape, as the epoxy will not bond to the glue, and fill in using epoxy with a bit of silica filler. I also sealed the entire cut-out for the port with epoxy, as Hunter had not done this. I had some rot to dig out and fix.
