Well, managed to get more cut out, got all the panels cut, and the side panels drilled and attached, with a hole on the back to access the links too. Just need to bend the sides back into shape because the radiator the HDPE stood next to heated it up, and I never realised it until I tried to bolt it together, so more than likely, I'm going to try and bend it a little more haha. BUT progress has been made!
