I helped a buddy find a 3rd party lower pan to fix a broken drain plug hole. He's has the M62 it cost like $60-70.

You can get self-tapping fix plus but I don't love the idea because where do the metal shavings go?

The V8 has a two part oil pan and the lower part is a very straight forward replacement.

The trickiest part is torquing the bolts properly. Screwing steel into aluminum is always a bit risky. Most torque wrenches don't go down low enough. When I put an oil pan on recently I used my 1/4" drive Impact driver on "hand tight" mode to snug everything and then some additional torque angle (like 45 or 60°)
