I have foam insulation from my slab extending above grade. It will be getting covered, and flashed.

I will be doing an end dam where it meets garage doors/man doors. However I will need to cap the openness below the end dam to keep moisture out of the side. It looks like I'll have to cut/bend a custom cap piece of sorts.

Any recommendations/has anyone needed to do something similar?
