There are 3 Cadillac pans, the stock front sump, the El Dorado rear sump which is fairly rare, very deep and expensive and then the route I took. The 425 Cadillac mid sump which is more to the rear than mid will fit just fine, looks a lot better and has the same bolt pattern as the 472/500. You will also need the 425 oil pump pick up tube. These pans are pretty easy to find and don't cost too much. If it's going on a 500 you may need to GENTLY clearance the pan at the 2 front crank throws due to the extra stroke. Here's acouple of pics of mine if I can find a decent one. OOOPS, sorry bout that, the second pic had been resized and screwed it up. If you go to www.500cid.com and join the forum you can get loads of info from big block Cadillac guys and probably find the pan you're looking for....good luck
I've never tried one but I hear it will fit, you may have to do a little re-work to the pick up tube. The 368 and 472 has the same stroke so there shouldn't be and pan/crank throw clearance problems. Also I see someone has an Eldo pan for sale, just FYI, the Eldo pan has something like a 9" deep sump....ground clearance may be an issue.
