well it is safe to say that cbs was using the same patterns for the mustang so things like routes and shape should be almost identicle to pre-cbs and the tremolo units are the same, the main difference is the grouding method and the cloth wire vs. plastic wire.
the tuners were just kluson deluxe knockoff's
things like strats and teles were getting re-invented every 4 years.
same with the jaguar and jazzmaster, but they didn;t get as nasty as a 79 strat or a 78 tele deluxe.
