Thanks for your comments.
I was thinking of shimming, but the bridge raises the strings a 1/4". Yes the bridge does come off the studs, but I looked at a few Wilkinson roller bridges that I have, and they are about the same size. I'm just gonna send it back. I filed down the existing ashtray too work.
I just have to wait for a diamond hole saw set to arrive to extract the broken screws for the Extrem Vibrato. Three of the heads broke off. One when installing, and the other 2 when trying to take them out. Never had that happen b4, and I have installed a few Bigsbys.
