Thanks for the info on the engine cover attachment. I've been brainstorming ideas lately since I'm working on the body now. One idea I had was to glue some U-channel aluminum to the underside of the top of the engine cover (so the legs of the face down), then take another piece of u-channel and glue it just below that, facing up, on the side sail. The legs of the U would overlap. Then drill a hole from the cabin side through the side of the engine cover and through all four legs of the u-channel and secure with a quick release pin. Your way sounds easier though!
