Actually, I'm in the process of moving the tips from beneath the water line to above it. I got a reply from Stainless Marine yesterday and they said they'll fab em' up for 130.00 each. That's all the detail I have from them at this point. I don't know if for that price they come with flappers, etc... I would imagine that they polish them when they are done though. I'm gonna have to call these other companies that you guys have recommended.
Stainless Marine did custom tips for my brother's boat and they were perfect.
