Relentless Fab Hinge CB/AUX. Mount - Will it Fit a UHF or NMO?

Im wanting to buy the Relentless Fabrications hinge CB/Aux mount. The entire bracket looks like it was designed for a firestik type stud, but I'm wondering if there's room for a UHF antenna mount or even an NMO mount with a little drilling? I dont want to drill a hole too big and compromise the tab. Thanks

Below is a UHF antenna mount:

 

Hmm, the other mount they have that goes on the rails says it's a 1/2" hole, but doesn't say with this one.

@RelentlessFab ?

 

The hood mount's antenna mount ear is 1.25" square, the hole is centered in it and 1/2". Theres room to go up to maybe 3/4" if you wanted, but I wouldnt recommend drilling larger than that as it would start getting pretty slim around the edges.

 

Thanks 3/4" will work for the UHF mount.
