Kona kayak questions

I just purchased a used Hobie Kona kaya.

I have replace a few parts but I have a few questions

1) locally I can get scupper plugs for the Ocean kayak but they have different sizes. Does anyone know if any of these will work in the Kona?

2) I am working on the replacing the hooks that are used for the shockcord. I have put some on but in the front the bungee hook doesn't seem to fit. The place where some kind of hook should go is round and the bungee hook won't allow for the shockcord to be slipped underneath it. What kind of hook is needed? I bought the part number 78510001 hook. I have pictures but don't see a way to attach them to this post.


Thank you
