This is a replacement part for the Traxxas model Rustler. Not much testing has been done on this part, so it is a work-in-progress.

The Rustler is a 1/10 scale Truggy, made by Traxxas. http://traxxas.com/products/models/electric/37054rustler

In case you can't tell, the part is the green part on the car. I'm about 80% certain it will work as a suitable replacement part.

Do you want instructions on how to make the part or how to put it in place? I'm confused.
