I've had the same problem even with a model made 35 years later...I think Ford screwed up in designing the wiring for the tailights in particular, I've always had the problem in both my 96 GT and now 01 GT with the rear blinkers coming out of sinc or the bulbs burning out. Check the fuses and make sure they're all ok, next replace any burned-out bulbs and see if its' only that and not the wiring...for $10 or $12, its' always worth it..the bulbs will never go to waste if you don't need them right away. Do '66 Mustangs also have that annoying seat belt problem?..The stupid thing is constantly jamming on me.
