Here is our old oil pan next to our junkyard fresh replacement. We had a bit of a hard time tracking down a used oil pan, even though apparently a Dodge Dakota of similar model year will work on a TJ. No one was selling one. Also, Mopar has a replacement oil pan for the 2.5L (PN 53020560, $180), but we eventually tracked one down at a pick-a-part junkyard. Initially we were gonna weld a skidplate on the bottom of the new pan, but after thinking about it, we decided to build a skid that tied into the center skidplate and frame.
