did the 66 fastbacks have turn signals in the front? from the pics ive seen it looks like they do. Another thing, do i need front turn signals to pass inspection. i know that since the car is 40 years old they arent as strickt with the requirements. and some other things would be. what is the piece underneath and front bumper called? and what is the piece underneath the rear bumper called? and where can i get them? and also what are the lights in the front inside that piece under the bumper called? and where can i get all of this? itd be really awsome if any of u guys could post a link! -thanx for the help

 

Yes they had turn signals. Yes you need them unless you want to use hand signals and/or get pulled over a lot. The part under the front and rear bumpers are called valances. You can get this stuff at any on line mustang vendor. The lights in the front valance are called turn signals.

 

You can get the valances and the turn signal lights and brackets here.
