Thanks for all the replies. I didn't completely describe the job. The reason i can't use water is that i also have to cut out the two tubes that the mounting bolts go through. The bolts have been impossible to get out; so, i was going to just cut the tubes out and replace them at the same time.

I will probably have them thoroughly boiled out, then use the CO2 from my fill bottle. I can regulate it down to a slow flow and do the job. I wont take too many chances; didn't get to 60 by doing stupid things (well maybe i was lucky some of the time:p )
If i could afford it i would probably have it professionally done.

On the other hand, that would defeat my argument to my spouse that by having my own MIG, TIG and Plasma Cutter, i could do my own work. I really have done a lot of welding, but this is a little different than roll cages, hitches, racks and such.
Thanks for all the suggestions. Jimmy
