I made two 4 sided boxes out of thicker sintra and superglue, then put a back cover on it with thin sintra. The boxes were made to fit the 2 boards perfectly. I just use clear shipping tape to hold the two boxes to the back side of the armor, the tape is very strong and super easy to remove. This works like a charm, doesn't take very long, and adds protection to the light board which is good cause they sure ain't cheap. I made cut-outs in the vest to make the armor sit flush and hide the wire band. I 've been meaning to sew in a tiny piece of velcro into the vest to hold the battery securely too. I'll just slap a tiny piece of the sticky backed velcro to the battery itself.
