Does anyone know where I can get a low cost steal, or a plastic or composite timing chain cover for a 3.0 Merc. A freind told me he has heard of non-metal ones that will never rust. I was looking around and could not find one. $200-$250 seems like alot for a stamped piece of tin. I saw stainless ones for a small block chevy for $30. Any help would be appreciated.
