Stingray 5 Bridge Help

My dog pissed all over my #1 Stingray. I need to take it apart and give it a good cleaning. I can’t figure out how to get the bridge off, It looks like, other than the 3 screws towards th e back, It’s attached using screws through the studs on either side of the B and G strings. I’ve tried a few different screw drivers, allen wrenches, torx bits, etc. but nothing grabs.

Any help is welcomed.
Thanks!
