As you see, the P90 has two mounting screws in the middle of the pickup. I am installing a DiMarzio that has the mounting holes toward the outside, like so... The issue I see is that one of the screws to mount the pickup will go through the wiring channel, which is fairly deep. Similar to this (obviously this is a humbucker route, but the channel looks to be the same). Is the right thing to do to glue a wood block in the channel, or try to get an extra long screw that will reach the bottom of the channel so I can grab some wood? I don't have the pickup yet so I don't know how long the screws are that come in the package.
