I have an ESP LTD B-55 that is several years old. I would like to replace the single coil bridge pup with a stacked humbucker, but the problem is that the screw tabs are not a standard size. The distance between the hole centers are 1.76 in, and everything that I find seems to be either 1.57 or 1.91 inches. Does anyone know where I could find something that would fit this so I don't have to route the top, or if it is possible to remove reuse the cover and replace just the coil? I have tried asking ESP customer support but they don't seem to feel like getting back to me.
