I spent a lot of time a fews years ago searching for cap replacements and couldn't find any. It seems that in 1985 Ericson for some reason went cheap when selecting deck fills. I ended up replacing the whole unit, I think the brand I selected was White Cap, or something with a similiar name. Anyway, there are several brands available all of which appear to be heavier duty much better made than the originals. BIG WARNING: removing the deck fill unit is not easy. It takes a lot of muscle, technique and time. Had I known how much work it would, I might not have tried it . However, I'm very please with the new deck fill. It looks a lot better, and works a whole lot better too.
