I just replaced my drivers side pan yesterday. I added two thin small flat washers to the oil pan bolts, and a bit bigger on on the bottom side to take some of the stress off the flange on the motor pan, and add clamping area. Is you hold the motor pan up to an oil pan that is sitting in your garage floor you can see the benefit of this. Costs about $1.50, but the benefits are greater than having to re-fab and weld in new material down the road.

Pan goes between the top two flat washers, then the motor pan tab, and then the underside has the slightly larger flat washer (which I ground a flat edge on) with the lock washer. Don't go nuts tightening these bolts to the oil pan. There is still a gasket in there to consider.
