I have an '07 rappy 700 gytr that I've only had a few weeks, but still managed to bash it a little after a day or riding. I bent the left upper ball joint (bent the ball joint itself). What's a decent drop-in aftermarket arm, preferbly with replacable joint (WTF would they ever make it so they sould not be replaced). Anyone have an idea how much a stock one goes for? Thanks, Greg.
