Anyone know where to get a compatible mount for my Throttle quadrant?

New pilot here, in the middle of my ground school and finally getting set up with MSFS to dive into VATSIM for practice.

I ended with a hand-me-down Saitek yoke, and a Logitech throttle quadrant, but the throttle quadrant didn’t come with he mounting hardware. When it was used, it was just velcro’d to the top, which is fine, but I have enough desk space to have it mounted to my desk.

I’ve found a bunch of HOTAS mounts, but I’m not sure if any of them fit the screw-lay out of my throttle quadrant, as I haven’t seen it in any of the mount examples. Does anyone have a solution they use? or maybe even a spare mount from there Throttle quadrant they aren’t using anymore?
