H.D.G. is right, that @$$ gave you the wrong gear....

They aren't interchangeable between Associated models, but here's a bit of info.... in a SERIOUS PINCH a nitro-Evader spur will BOLT RIGHT UP. No changes.

Evader guys, this goes for you too... They don't make many (if any) diff. size spurs for the Evader but the RC10GT Spurs will work!! On the Evader they can't be much bigger than stock or they will rub but you can go smaller (more top-end) with no problems.
