These NOS Classic pre-formed chassis rails combine with the Classic Serpent motor mount available in this catalogue (part # CLA-SER1), the Classic Serpent drop arm (part # CLA-SER2) and a piece of K&S brass tubing to form a complete original Serpent chassis for the available reproduction bodies out there. Solder them to the motor mount and the brass-tubing front-axle holder and you are done!
Sold as a set of 4 rails.
