[DeTomaso] Galled stainless fasteners

[Thomas Tornblom]

Perhaps you can try the trick Tomas Gunnarsson and I used for getting 
the stuck drain plugs out of my block?

We placed a suitably sized hex nut over the plug and welded it to the 
plug with a MIG-welder through the threaded hole. That serves two 
purposes, get something to wrench on, and heat the plug/bolt so that it 
will be easier to get it loose.
