I'm trying to remove the pickups on this old Supro for a guitar build. I can't find any screws on top of the body, back of the body, on the pickup rings that might hold the pickups and rings onto the body. I've tried unscrewing the outermost screws on the pickup itself, but that just adjusts the height of that side of the pickup.
Any ideas on how to remove these without breaking the pickup rings to get to the guts of the pickups?
(probably not attaching an image or URL properly below- but I'm sure you guys know what the 50s patent Valco pickups look like right? Humbucker sized, but single coil)
Thanks in advance for the help!
