Chevy guy with a Mopar? hmm...

cool cool, well you can go built stock or you can buy a bolt in front end. Going thru the stock front end is MUCH cheaper than say an RMS front end, also by going thru a stock front end you wont have worry about the harshness and longevity of heim joints.

on my 73 swinger im staying stock front end, but going Poly bushings, adjustable strut rods, and new strut rods. This with heavier T bars and good shocks and you'll be YEARS ahead of the stock suspension but wont have the price tag of the RMS (6500 as i recall).
I really like the k-member HemiDenny has been developing. Simple, strong, really clean looking. Uses of the shelf parts for a fraction of the cost of other aftermarket kits.
Finally got around to making a build thread for the Dart
