1970 Dart with collapsed suspension...

now the suspension is way low in the front

Some photos of "way low" would be very helpfull.

My 67 dart with 215/70R 14s sits like this.

Now /6 tortion bars are not as stiff as V8 bars so that could account for some additional low in the front.

On a side note the down bump stop on mine sits 3/4 to 1 inch max from the frame pad
