VKB-SIM

I just ordered the STECS max and gunfighter iv MCG-U.
I have these mounts for my old hotas:
DIWANGUS thingies
Can anyone tell me whether they're compatible with VKB stuff? I couldn't find any pictures of where the holes are for VKB or what kinda screws they use.
I probably should've asked before ordering but eh...

Oh another thing, what's the usual time for shipping? The order was marked as shipped on the 21st (same day as I bought) but UPS tracking still says they haven't received the package. Nevermind, it's on the way now.

And now that it's here I can say, nope does not fit.
STECS could fit if you don't have the max but the diwangus screws don't have long enough threads to tighten it properly.
The stick base could fit if you use the VKB screws that come with the base but it'll jiggle all over the place.

Anyone here from the future, get a different mount.
