Can't locate these in stock anywhere so maybe someone has used pieces or a set they'd part with.
Comes from/fits Diner, Whirlwind, Bad Cats and Roller Games.
The RED Parts Catalog says:
03-7578-8, Side Molding, 17-7/8-in (2)
03-7578-9, Top Molding, 27-in
03-8045-1, Bottom Molding, 27-in
My WW is rigged with later parts of the wrong fit and size so I know from experience that parts not designed to fit with mylar translites don't work very well.
