Clutch covers and part numbers, witch years fit witch ?

[poelinca]

I'm in the market for a new clutch cover. The manual states that the part number i'm looking for '14 is ME22010GG.

Seller A states that the same part number fits '12 to '15. It also states that ME250732002 will fit 96 to '11. It also states the different part numbers for the '14 and '15 models are because of a new alloy used, but the shape did not change.
It also states that the clutch cover gasket ME22015GG will fit '00 to '15 models.

Seller B states that ME250732002, ME15000003011, ME250332002, ME25632002 and MFS450732002 will fit 96 to '13. It lists separately the ME22010GG for the '14 model (that i'm after, and does not have one in stock).

Seller C states that ME22010GG, ME15000003011, ME250332002 fit each other.

Who is right and who is wrong ? Because the overlapping '11 do '13 years means the same clutch cover will fit 96 yo '15 and that is hard to believe.
