I am missing the 4 inch deck plate (screw in/cover) over the anchor rode locker on the bow of a 30' pearson. I picked up a new one from West Marine thinking I could just use the screw in/cover portion with the existing flange (female part). Unfortunately the missing one and existing flange is slightly smaller than 4 inches and the new one won't fit. To use the new deck plate I will have to completely remove the old flange and possibly make the hole a bit bigger to install the new one. Not really a big deal but don't want to do this if not necessary. Does anyone know the manufacturer of the original deck plates so I can find a proper fitting replacement?
