'96 336 Lewmar portlight sizes

[Techstyle]

I am trying to Identify the Lewmar portlight for the '96 336 bathroom and Bedroom from Lewmar's size chart. I measured it as 15.5" x 8.125" when measuring from the inside, only when I got home did I see they wanted me to measure from the outside. Anyway this chart states it is likely a size 5, can anybody confirm?

OK, Sounds good - I also need the seal for the Portlight in my aft cabin which is a Beckson 512 (Ports and Parts) (Beckson Port Replacement Gasket - 5" x 12"), they seem to be on Backorder - do you know how long and will you match the defender price? (Beckson Port Replacement Gasket - 5" x 12")
