steve,
a 33 at my marina was retrofitted this year. i think he is an '04 or '05. they were custom made plates, since the refrigeration connections had to be located in specific spots due to other equipment in the bilge area. also, they have a stainless steel case since the plates have to go inside the fishbox rather than around it like an OEM install. next time i see him i will let him know of your interest and he may post something to you. ron
