Can't Find the Right Replacement Clutch :( 2004 BMW X5 3.0 l6 6 Speed

[Hochstein]

Hey Everyone,

Sorry to join to ask a mere question, but I have ran out of places to turn.

My clutch recently gave out on my 2004 BMW E53 3.0.

I ordered a LUK 03-078 clutch kit from Rock Auto (was classified as a compatible clutch for my model). However, once the transmission was removed, it was clear this clutch would not fit. The pressure plate looked much different, and the disc itself seemed to be too thick (as we considered just using the original pressure plate as a last resort).

It seems it is pretty rare to find an X5 with a manual transmission, but does anyone know what type of clutch I may need to get?

The pressure plate had this number on it: E63 08

The disc had: 21.27-7 526 600

I also attached a few different photos of the factory clutch.

Thank you in advance for the time/help! Cheers!
