I have trouble finding out if there were any visible changes to the Fender Jazz bodies Fender produced from app. '63-'69.
Before 1963 the grounding wire to the bridge was external, so the missing body routing will identify those. In 1970 the bridge pickup moved closer to the bridge and the routing for the grounding wire under the bridge got larger.
Did anything else happen from '63-'69 (besides finish changing to poly)? It would be nice to be able to date stripped 60ies bodies a bit more precisely.
