What are these upright mounts used for?

I’m getting close to finishing my build and don’t know what these upright mounts are used for?

Thank u

Is that used to mount the rear wing? The slots look like they are for wing angle adjustment. I don't have a wing, so totally guessing.

Wow awesome! You are correct they match up to the mounts perfectly. I have my wing on order so hopefully within a week I’ll be able to mount it.
