Part Numbers for Mount Kit for 2.5" Drive for Latitude 5491

I'd like to install a 2.5" SSD instead of current M.2 2280 SSD in my Latitude 5491 (I'm pretty sure they won't fit both, so 2.5" SSD alone is OK). If that matters, my hardware configuration has built-in Intel GPU (no Nvidia, no Thunderbolt), and appropriate space for mounting of 2.5"drive, but is not equipped with SATA cable and a mounting bracket.

I found an Ebay lot with SATA cable and caddy frame bracket for 5490, 5491, and 5480, and it mentions respective part numbers: 80RK8 and 0NDT6.

Are these part numbers correct for Latitude 5491 and will they work with it?

I contacted my local authorized Dell service center, and they said they can order the parts, but they don't know the exact part numbers. So that's why I'm asking here for help.
