Yeah, I was planning to have a kind of harness under the vest with clips or something connecting to the underside of the backplate.Looking really good so far! Just be sure to reinforce the areas around the pegs and holes and you should be fine. Getting the holes and slots to line up is a little tricky but it's not too bad. I plan on having those pegs mounted to some kind of strapping/harness and slide the backplate over them. That way the weight of the JP isn't pulling the backplate off. Unless you find a way to securely attach the backplate to your costume.
