OEM rear sump oil pan?

The Ram oil pan is steel, i would prefer aluminum if possible.
You might have to make one then. I can't think of a rear sump pan that's aluminum. Even the swap pans are made of steel.

If you want a ram pan complete with pickup and such I have one. It has some bottom damage...however you could use your pan up and use the mounting surface and build a new aluminum one.
