Dashboard voltage regulator for 1964 Dart 170

New to the forum...but have spent hours hear reading strings on this. STILL can't figure out if my model has the regulator built in to the gas gauge of separate regulator. Not the greatest mechanic...but this is driving me crazy. Already have the part that the auto parts say I should have but...where the heck is it in the car? Any help will definitely get you on my Christmas card list! Thanks, Bruce IMG_20191110_121740171.jpg IMG_20191110_121740171.jpg
