Twist in style bulb holders for turn signals I just parted out a 78 Chevy pickup and made an astonishing discovery.....the front twist in style bulb holder will fit the late model one piece plastic turn signals on Mavericks! They are turn signal/parking lights. There may be others that fit also, but I know firsthand these will work, you will have to wire them in as the plugs are different. This is another option if you can't find FORD replacements in your area, just swipe some from a Chevy truck and don't tell where you got'em!
