I had a new MIM Fender P bass, roasted maple neck, sent straight from Fender. I dunno if the I"s differed from the II's. I had no problem with fitment. Had to drill different holes and puddy up the others. These guys I tagged should know.The pro I neck is the same bolt pattern as the replacement neck.
Were there any other issues with the way the neck fit the body? Any pictures of the mounting area?
