Up for sale is a vintage Trinity Evolution 10 EV0012 Super Speedway Front End Kit. Trinity started selling these after the success of the Evolution 10, as upgrade kits for other pan cars, like the RC10L SS. Yes, this kit is compatible with other cars. This rare kit is a must-have for collectors and hobbyists. I saved this for many years in my basement, so the box is not in the greatest of shape, and the front end kit could use cleaning. But it's complete and still in good working condition. These conversion kits are a rare find, and something many of us kept as spare parts for our on-road cars.
