Final answer....Stock replacements are all you will need. Unless your going for the Joe Dirt look. :)

Pair them up with a new set of Monroe or KYB shocks all around, and your rolling.

Stock height springs, you will be happy, your Dart will sit like it did when it was new. And the handling will be as it was designed to be too.
