rings

Does anyone know the manufacturer of the original deck fill fittings, or the replacment oring size for the caps. The 1-1/2"IDx1-3/4"OD 1/8" material is to big. The consequence of using the wrong size or one that doesn't seal on the Diesel fill, could ruin your day. Thanks Rich s/v Breeze...

I own an E32-3 (1987) #713. Does anyone know if the beige trim rings that fit around the portlights can be replaced. Mine are cracked and falling apart so I am afraid to touch them.
