Re: Mounting pick up to body?
I direct-mounted a soap bar P-90 into an SG. I'm not thrilled with the foam rubber arrangement. I got a pack of shims from Home Depot and used several in each PU slot. Because they're wedge-shaped you stack them and get the height you want. I screwed them into the body, and then screwed the PU into the shims. Not hard to do. You could glue the shims together too, and then screw the whole thing to the body, or just glue everything.
