So, I got myself a "moon fret inlays" Korina Singlecut SE, and I've been doing little work on it. Pulled some minor dents out of the fretboard, cleaned up the frets, threw some Schaller locking tuners on her, and I've got some Duncan P-Rails on the horizon...but in the meantime, I had snagged a TonePros AVT2M-C bridge. Got her in, went to install and...the studs won't thread?

I'm wondering if I was sent the wrong one by mistake since everything I've read said it's a direct swap. Can anyone in the know tell me if there's a way to tell? Thanks!
