Thank you for looking at that! It’s what I suspected from looking at it installed, but wasn’t sure and didn’t want to undue mine just to have a look. My ‘15 works so well I’m hesitant to mess with it.Ok, I just checked out the Babicz spacer plate and it is indeed flat, it is also nearly twice as thick as the Eppi shoulders are high. Unfortunately, the bolt holes in the spacer are sized for a slip fit of the Eppi/Gibby bolts threaded section only. To clear the Eppi shoulders the Bab spacer holes would need to be at least .625" diameter. If you tried to drill out the spacer holes to fit over the Eppi shoulders you'd quickly run out of meat on the spacer plate (see pic below).
In other words, the Babicz bridge will not work on the Eppi unless you intend on mounting it above the body on top of the Eppi shoulders, which leaves a 1/8" air gap and kind of defeats the purpose of having a full contact bridge. Stick to the Hipshot on the Eppi and the Babicz on the Gibby.

I’m going to wait on the Hipshot for the Silverburst from the seller I ordered it from as I got a reply from him today. He’s promising it should be in from Hipshot any day and then out to me. Forty bucks saved is, well, forty bucks. But next time I’m ordering direct....
