I have a Dirt Jumper II ' 04 6" travel. I need to increase the rebound hydraulic damping, but i don't have and i don't know the size of the hexagon rod. The rebound adjuster is located inside the stanchion tube. The rod is supposed to be long, so maybe somebody knows where I can get this hex rod. The most important for me is know size. If somebody knows someting about how to adjust rebound, please help me!

thanks a lot!
