Hey folks, I searched but couldn't find anything specific on this. Im switching out the pups on an SX P bass and having trouble with the height. On the stock pups there are springs on the screws that hold them up. The Basslines I'm installing fall out of the pup covers into the body route. I assume there's something I should be putting under the pups to hold them up. I don't recall if the Basslines came with anything other than the screws. Thanks
