Before I watched the video, I had filed a few scale inches off the top of the air cleaners (rather than remove them) to get the hoods to fit better. The blue Cascadia required more filing than the white Cascadia. But even then, it appears the cab of the blue Cascadia sits back a little further on the chassis so the fit between the hood and the cab is not quite perfect when you view it in a photo that is several times larger than the model.
