I went with a style of diff cover that didn't use the factory Gasket, but Black RTV. I'm ending up switching to a different style of diff cover that does use the factory gaskets, and I'm having to buy new gaskets for them. After a while on Google this is what I found, and the fitments on Mopar's website for these parts seems to be a bit questionable. It lists all the years and trims of wranglers for all the part numbers, and that can't be right. I'm not sure if the axles changed mid year, or not, but mine is a 2020 3.0 EcoDiesel Rubicon, and I know I Have the M220 rear and the M210 front (both D44). If you are looking at this list of part numbers, you should verify it fits your year and trim before buying these part numbers. My intention is to provide a starting point for these parts.

Looks like the rear Gasket is the same for all trims, you should verify this in case something changes.
