Hi guys, I bought the UCM-S for the Gladiator NXT in preparation for MSFS 2024 but the only guide I can find to mount the NXT to the mounting plate is for the EVO https://imgur.com/a/nxt-evo-to-ucm-plate-2FU4IvB. My Gladiator Next (regular) doesn't have the hole in the middle. How do I attach it to the mount plate?

Ignore this post, I bought 2 UCM-S mounts and thought I was working with the one for my Gladiator NXT but it was actually the one for my STECS lol

The central hole (the one marked in the guide with 'countersunk screw') is actually for attaching the 2 plates together. The Gladiator gets attached to the top plate with the screws (3 or 4) at the corners only.
