Best way to attach a foil rails to a normal board?

Gong foil arrived. Much more solid and way stiffer than I anticipated. Has anyone of you guys installed foil rails on a plain windsurf board ?

Is this difficult tot do ?

Any hardware / rail brand recommendations please ?

Axgib and myself have zero experience in this.

Thank you.

I also have a hydrofoil Gong with a deck for rail US box, I thus ordered box and rails to Gong here is a link with photos of the installatio in the course of this US
