Most bridges share the same layout for the screws, so positioning it shouldn't be a problem. You can (or should) always check the intonation after you've fitted a new one.
Be aware that under the bridge there's an unattached wire that seemingly does nothing except disappear into the control cavity - this is an earth wire and needs to be there. It's practically impossible to solder this wire to the bridge (which, in this instance acts like a mahoosive heatsink), so it's simply trapped betwixt body and bridge. Hey, it's good enough for Leo Fender...
