Whatever you do dont buy pickups from a guy named bjsturm...that guy is a dick. Just kidding. Anyways Im assuming you may be the one that asked about my 2 Jackson Fusion pickups on ebay. If so I wont be home to check on the exact measurements but i sent a message back and I think its got to be close to that: private:.
I have one. Send me your mailing addy. If it works for you , I'm always appreciative of set of strings or whatnot. Condition of pickup and cover isnt perfect. Its taped -its a staggered stacked humbucking S/C pickup out my Soloist XL Pro. also Wires need to be soldered to bottom.
I have an old J100 out of my old Kramer....I am in Canada though so I am not sure how easy it is to get to you
got a J90C here if you want? from England.
also have a cover somewhere.
