I want to replace the old galvanized fuel tank in my 1977 28ss. As far as I know the rear tank is 70 gallon and the bow is 30 gal. Does anyone know if there are replacements in either aluminum or poly. I am not sure of the dimensions, but any help would be apreciated.

The tanks in my 1978 cig 28ss were replaced in the 1991. with replacements from I believe what is now RDS. They should have the Blueprints on file.
