What SSD will work in my late 2012 iMac PCIe 7/17 socket

Hi

I have a late 2012 27” iMac

Serial no C02KD9RSDNCV EMC no 2546 model A1419.

I want to add a SSD into the empty PCIe 7/17 socket, I have searched the net for a blade type SSD that will work, I have found 1 or 2 that are supposed to work with mid 2012 to early 2013 variant, iMac like

1.0TB OWC Aura 6G

Solid-state Drive for iMac (Late 2012 – Early 2013)

Mfr P/N: SSDIM12D960

OWC SKU: OWCSSDIM12D960

or

Mid2012 - Early2013

MacBook Pro A1398 A1425 SSD

口128GB

• 256GB

512GB

1T8

P/N: MZATEA 1398 HMHP

S/N: 20208112021398

MODEL: MZ-A1398A1425

but the model number given is A1418, can anyone tell me if my model A1419 is compatible?

If my iMac will not support these drives is it possible to use an adapter to change the 7/17 socket to one that will accept a more readily available SSD?

If anyone had upgraded there iMac either with a module that will go into the existing socket or used an adapter that allowed the use of a more readily available SSD, could they post the part numbers or name of the hardware they used.
