Dark Rock 3 W/O Backplate: Will an aftermarket plate work?

[collinchattom]

Hi, so I'm currently building a PC with the ASUS ROG Hero VIII (which has an LGA 1151 socket), and the Dark Rock 3 cooler refurb I purchased did not come with its mounting backplate or its 4 M3x15 screws.

Considering Be Quiet! is in Germany, even if they will ship it out just for ship cost it'll be from there to here in the US, and it'll take quite long. I was wondering if an aftermarket mounting backplate for this socket (like this one), and set of aftermarket M3x15 screws (like THIS one) would be suitable for for mounting it.
Unless, there happens to be some super sneaky place I could purchase the brand Be Quiet! mounting hardware.

Thank you much in advance

Do you have parts that go on cooler's side including plastic spacers ? If yes, in that case you could adapt any backplate that fits 11xx socket. Might have to improvise with screws.
