I'm trying to install a pair of Gibson humbuckers on a Brian Moore guitar. Because of the closeness of the top to the strings, I have to lower the pickup beyond the 1.25" length of screw that was supplied with the mounting rings. The original Brian Moore pickup had a lip on it that was about 3/8" closer to the top of the bobben than the Gibson pickup. I notice that Dimarzio pickups are made in a similar way. I've tried all the guitar parts stores and many of the online fastener stores. I *can* find 4-40x1.5" screws. Is my only alternative to tap out the pickups for 4-40 threads? I know I can't be the only person with this problem. Any help would be appreciated.
