Had this happen before, and all I did was remove the spring and bent the shaft straight in a bench vice very carefully. Depending where the damage is, it may not apply to your situation, but I haven't had any issues with it since.
Give Frank @ ShockTec a call. Have been very happy with service and even sold me the tools needed to get me started on doing y own rebuilds. Helped with any questions I had and revalved to my weight/riding style.
