Chris,

I bought a 300D a few months ago and I had to repair 2 of the jack points on it. I fabricated the sheet metal and MIG welded it into place. The trick is to cut the hole for the jack point fairly close to the diameter of the jack point and weld it onto good shiny metal. Mine weren't too bad and took me a couple of hours for each one. The good news is that the repair, if you choose, doesn't have to be perfect cosmetically because: 1) It will be down low on the car and B) covered with a flat black mottled undercoating.
