Traxxas Stampede RC4WD Predator tracks adapter

I made this because I wanted to use the RC4WD Predator tracks on my Stampede. Unfortunately, RC4WD doesn't make an adapter for Traxxas. I've used this on my 2WD Stampede and it works great. I drive in deep snow across the yard. You can see the 2 holes on either side of the adapter. These are for 2 small 1/8" wood screws that give it extra strength.
