What size bulkhead does this use for the hole on the aquarium itself? It states the drain bulkhead sizes but not sizes for the aquarium itself.

They provide hole saw to install overflow.

Is there anywhere i can find the mounting template for this overflow box? i’m trying to see if it’ll match the holes in a synergy reef shadow

I have not seen a template online. The holes on bottom fit 3/4" bulk heads and pvc. I believe the whole on the back with the mounting bulkhead is 1 3/8". My partner and I drilled our own hole for mounting based on the size of the bulkhead and hole on the back. The product does come with a glass cutting drill bit for making the correct size hole.
