I have a Pearson 365. I plan on replacing my port lights with ones from New Found Metals. They aren't cheap but they are really nice. The PO replace the two larger portlights with NFMs. Now all I need to do it replace all five of the smaller one.
I have no suggestions on your odd shaped windows.

Difference between a power boater and a sailor out on the water: A power boater is going some place special, a sailor is already there.
