I am rehabbing a 1997 Performer and have run into a problem I would appreciate advice on how to deal with it.  The dampers on this unit are badly rusted and I want to replace them.  I have the Weber kit and all I have to do is take off the old and put the new ones on.  Now here is the problem I can't get the control rod out of the "H drive".  They are rusted together.  If I understand the way these old dampers work, it is the control rod that holds the assembly together by running through the "H drive."  I ahve used PB Blaster, but so far I can't budge the control rod.  I can not pull, push, or twist the rod.  I have hit the H drive with a hammer a few times and have heated it with a torch.  This has not yet worked.  I have not tried putting a cheater bar through the loop on the control rod and trying to twist the rod because I am afraid I will break the rod and that might make it harder to get out.  What do you guys suggest or think I should do?
