Transfer Case Flange; Front? Rear?

[Yellow Cake Kid]

Hi,
I had new 1350 style driveshafts installed with my lift and when the guys gave me the transfer case flange take off parts I lost track of which is which. They look pretty much the same.
The parts are off a 2020 JL unlimited Rubicon Rock-Track(?) transfer case.

They do have a single digit difference shown in some of the engraved labeling but the nomenclature doesn't seem to correlate to the MOPAR number system. Searching through MOPAR parts store websites left me a little more confused as the front case and rear case diagrams seem to link to one MOPAR part number.

Any thoughts on possible differences or label clues?

I'd like to label the parts and keep them available in case someone here in town breaks something and could use a quick fix etc.

Thank you!

These are the two transfer case flanges. The different numbers may be production codes, and don't seem to have anything to do with MOPAR part number I have found in lookup listings for "my Jeep".

These parts seem identical to me.

Are they interchangeable?

and

Thank you.
