Float fittings

Since summer 2021, I'm located in the great wet state of Minnesota – floats will be a way of life. I've always planned to add float fittings but the path has always been a little vague on how to get there. Like most aircraft, the front gear leg fitting is used as the forward mount, but getting a rear mount is a different story.

The options:

1. Add a gear attach just like the Barrows plans
2. Weld on a Cub-style float fitting
3. Do what this guy did: bolt-on fitting.

I'm growing partial to option #3 because it cleans up the fuselage when not on floats.
