Randomly adding components based on how hard I want to work at any given time. The alternator/PS mount is going to be a real pain, complex kind of random shape but it has to interface with numerous other components. 3d scanner would be real helpful, but then I'd have to scan it on the car because I don't have any spares hanging around.
Might tackle the exhaust manifolds next. Different view to prevent people from getting any more bored with this than they already are
