    Or any old piece of scrap iron can be welded on. The heat also
helps loosen things. In a former life I was a shop foreman in a
remanufacturing shop, and we used the weld-and-wait-15-seconds-and-
then-twist-it-out method almost exclusively with stuck stuff. The 15
seconds gives the heat time to penetrate and break loose any
corrosion. If it was in a zinc/aluminum alloy part, it was weld-and-
instantly-loosen, or risk melting the alloy.

      But the welding heat and sparks can set fire to oil and other
crud under there. Have an extinguisher handy. Stay clear of fuel
lines.
