I have a used deep aluminum sheet metal pan. Bought it used and it leaked so I took it off. You could probably use gasket sealer to seal it. Looking for $150. plus shipping if you're interested. My understanding is that almost all of these had a problem sealing.
My David Husek pan does not leak and is sheet metal aluminum. The flange is pretty substantial and I used a cork gasket torqued to factory spec over and over and over as the cork crushed and then check it every time I have the car on the lift. Doesnt leak a drop and its been on for a year.
