Correct configuration of bumper jack in trunk

Picture in post #11 is correct
They probably changed thing through the years.

Many photos were reused form one year to another. The jack head for Dart in my sticker looks different, probably from 66 or earlier.

@AlaskaJeff what year car are you trying to size up?

Post some photos of the front and rear holders with the jack removed. And the shape of your spring.
