Short of someone else getting back to you with a definitive yes or no, probably the best thing to do is to email Callaham with the exact measurements and see what he says. I've contacted him in the past about the possibility of replacing the entire bridge assembly with his, but unfortunately he couldn't recommend that unless I was prepared to fill and redrill the mounting holes. Not the answer I wanted, but I did find him very helpful. Turns out that the bridge plate mounting hole spacing on the Springy is just less than it is on the orginal.
If you do find out, be sure to post the result so that it's here for others to refer to later on.
