T7865 / T7875 Flexbay options

Hi everyone,

Asking here as calling Dell direct is getting me nowhere

I have a T7865 that's a standard SATA config, and I want to change the front bays to NVME, (if my understanding is correct, connecting to the 2 NVME headers on the motherboard)

Can anyone tell me the part numbers ?

I have found a version for the T5820 / T7820 which is the complete cage, backplane, and cables

And there is a huge list of parts number so I am sure there is a degree of interchangeability 

Part number - NKN20, 9FWHD, 02GPFW, 09FWHD, 0NKN20, 0RDCYK, 2GPFW, RDCYK

Thanks in advance,

Martyn
