She is a monster (thick/heavy).
How thick is the flange compared to stock? Just wondering as my skid that attaches the rear face of the cover would no longer work if the cover is thicker but I could shim if it was thinner...

Unsure how your diff skid attaches... When you say "thicker" it sounds like your diff skid wraps around from underneath to attach to the diff cover bolts.... Mine does... It is non-raptor D44 but if this is what you are referring to then it is the same issue... I had to do a little custom cutting on my diff skid to get it to fit with the new cover.... Was not hard. Made a cardboard template to mate with the diff cover and then used the template to mark my cuts on the skid...

You can see in the OP the thickness. I can measure it today if you want a number. I can't measure the factory one until I install and no TBD on that.

If you can at least measure the FP one I'd appreciate it.

Lots of variation. Odd. She is ground nice and flat but the thickness isn't uniform.

The thickness around the mounting flange varies from 0.26" - 0.30". Then the shallow counterbores for getting flat spots for the fasteners vary in depth from 0.045" - 0.09".

The factory Raptor diff does absolutely have a drain plug, it's just not on the cover. See this post.
