Advise: Going to look at a scamp

well, body to me is the most important. check for rust in the trunk, floors, under the hood, frame....
I personally like the traction bars, and I can tell ya through many, many years of experience, they work on mopars. There are systems that work better, but traction bars work. I have them on a duster right now, and when you brake torque just a little, the back end raises up about an inch. That's because the axle wind-up is applying pressure on the back tires. This pressure is what helps the traction, like adding weight to the trunk ..... without adding weight to the trunk :)
