Hi, all ... I have a 1983 Rickenbacker 4003 and am having some work done on it. At the body side of the neck, the two truss rods are apparently held together with a rectangular plate. That plate is broken: split down the middle into two pieces. At first, the luthier doing the work said he'd repair or replace the plate. Later he said that he adjusted the rods, has the neck in fine shape, and now doesn't think it's necessary to repair the plate. My question: is it OK to leave that truss rod plate split in two? Should it be welded together or replaced? Thanks.
