with that logo, serial number would be on the neck plate. The serial number went to the headstock when they started with 76 or S7/8.
Truss rod would adjust from the body too and there would be a plug in the headstock

You are right. according to Fender, the serial moved from the plate to the headstock mid 76 when that logo also changed. So, nothing on the back of the head but surely there should be a date of some sort on the butt?
