Looking for info on deck plate/access sizes. Everthing I see is 4,6,8, inches mine are 5.5 inches across. The old plates were made by viking marine in Calif. which seems to be out of business. The boat is a '89 Sunbird 173.Any one know where I can get this size plate? New floors/paint really don't want to cut holes any larger for fear of damaging six months of hard work!
