Help All You Duster Guys!!!!!!

Like has been said already, wait till the car is more assembled to see how the weight affects it. I had the same problem with my car when finishing the build, I've got SS springs with a relocation kit so I just drilled 2 holes in the front boxes to mount the spring in, a higher and a lower setting, unfortunately I had to cut off brand new perches and redo the pinion angle but if the 70's look comes back I just gota mess with a couple bolts:-D
