It pretty high tech so ill try explain as simple as possible (JOKE). I squeezed some liquid nail into the crack and onto the base. Lifted the bottom panel into place then used a nail gun to hold that then with my knee i lifted the side panel which had fallen to the right position then nail gunned that. I cleaned of the excess liquid nails with paint thinners on a rag once it had all dried i touched up the nail holes and the strip of glue with enamel model paint and a small brush. Simple but it worked.
