The engine cover does not fit well; I guess they figured most people would display it off the car (on the included stand). The panel lines on both sides look about like this, but at different angles… and the sides are much narrower than the tub. The leading edge had to be addressed too as it didn't line up or allow the opening for the fan to be centered over the fan. (Shifting the chassis is an option, but I figured getting the body set first was the better option.)
I used sheet styrene to fill in the needed material and modify the panel lines. Even though I raised the engine cover when I widened it so that the leading edge matched the body, I still had to add material to the top of it outboard of the fairings so the body would flow smoothly.
First coat of white primer to see how it looks.
