Here's a nicely made affordable bridge you may want to try with your whammy rigged guitar. Mount it to the body with the included studs and anchors. 51.89mm E to E string spacing. Post holes are 74.35mm center to center. Overall length 84.55mm, width 13.48mm. I measured 10.4mm height of the bridge base. Body anchors 11.71 diameter on the smooth portion, 12.10mm on the splined portion.
