I've done two, as has my brother John who will be at the Fest. Dan Topel of Topel's Repair can also assist. There will also be plenty of people around to help! It is fairly easy, takes about an hour to do. Make sure you catch up with me, and I'll show you my setup, as you may want to dupicate. We plasma cut a 2x3 inch hole near the back of the pan right under the oil plug. It doesn't affect the intregrity at all of the pan, but then if you put in a fumuto valve with a 8 inch rubber hose, you can reach up through the hole, pull out the hose, and open the valve. Make the oil change very quick and easy!
