The neck is not from 83! Only the serial number decal. That is a 22 fret neck and will not intonate on an 83 Fender body without moving the bridge. I just saw a guy on ebay buy one of these necks for $399 plus ship. The only body this neck will fit is a longhorn. The 3D tuners were available in 83 but I think they used up the extras on these basses. FWIW my 89 longhorn Jazz bass did not have the 3D tuners but my 89 P Bass Plus did.
