1970 Dart with collapsed suspension...

Just "some" possibilities:

1...Your perception, and it might be wrong
2....Suspension height might be cranked down on the adjusters
3.....Something might be broken
4.....Something might be rusted
5......Something might be bent, either from rust damage or accident
6....Tire size? Undersize tires can change things some............
I agree with all but especially number 6. I have my suspension cranked dang near all the way up with little tiny 195 70 14s and the front of my car sets way low. I like the stance but its too low imo
