Has a RMS sticker on it too. It must have at least some RMS parts on it.
My guess is a RMS front and rear setup. Just a guess. I don't see shock post through the inner fender. In one shot it looks like a blank hole. Also, I don't see a rear leaf spring segment behind the rear wheel in the picture with the left front wheel off the ground.
There was a previous thread on this last night. And a video link to the whole program showing some great vids of the Dart running....
I'll tell you, that RMS front setup to a shot when it ran head on into that ditch. And when they are jumping over stuff and really loading the car over to one side like that, it's tough on suspension pieces. A lot of movement, articulation, and impacts.
