Steering rack bolt

I am TRYING to get this steering rack removed, but the left bolt that attaches it to the car appears to be permanently fused to the tube thing where it runs through the cross member. I've already heated it hotter than the burnin' fires of hell, and it did finally get the bolt to turn, but the whole tube is turning with it. I've also beat the living daylights out of it with a BFH. So I'm stuck until I can get the darn thing out. I could just cut it, but I'd like to avoid that if at all possible. Anyone had this problem and a subsequent resolution to the problem???

I had that problem with my driver side tube. In the end I ended up getting the tube to come out with the bolt, and dealt with it outside of the car. For the life of me though I cant remember exactly how it went though. I do know I was sweating like a stuck pig by the time I was done.
