Total mod time - 5 minutes. I really didn't like that his cannon and blade were mounted on his upper arms, so now Shockwave can weild them on his forearms as intended. Please excuse the horrible cell-phone images. My damn cat broke my regular horrible camera. In this one, you can see the small round panel on the forearm that is perfect for the post mount to be drilled. Also, the pipe can fit snugly into a small gap between the wheel assembly and the back, rather than using the prohibitive port designed into the figure.
