I went to Walmart and bought a 110 volt hand held right angle grinder. Then I bought some cutting/grinding wheels (thin) for metal work. It went surprisingly well. Use a straight and a good marking pen to get as straight a cut as you can.
WOW! I love that extra inch. I can go over most any speed bump now. I actually broke my rear trans mount from hitting speed bumps before, so it's a great and needed modification.
I did mine laying under the car with it jacked up, plenty sparks.
