Hi Folks, wondering if anyone can help me with J-Bass Pickups.

I purchased some Tonerider TRJ1 pickups as replacements for ones that come in the JBA-4 kit.

I have now discovered that TRJ1 pickups are wider than the standard kit pickups. The biggest issue is that the mounting screw holes are wider also. I thought about using the kit pickup covers but the pole pieces are also spaced more widely.

Does anyone know anything about J-Bass style pickup sizes that can offer me any advice on what I can do? I really don't want to use the kit pickups.

Thanks,
Damo.
