Take it to Harris. I bet they will do a good. A friend did the same thing going over the top of one of our hills (the Hartman Bridge) and ruined the der. and bent the hanger through the center line of the der mounting hole. After getting oit close with a cresent wrench I had to run a tap in the hanger hole to clean up the threads.
I have the VAR ediion of the hanger tool to straighten it.
