highway vibration

actually i wanted to go with a 8 3/4 originally and the new rear is under the car right now and it fits perfect and the wheels dont stick out past the rear fender wells and i was planning on fixing the rear before i sold it but i dont like keeping parts in my car that have had problems. i dont really like the original width of the a-body rears since the front wheel base is wider then the rear. the e-body rear gives it a better stance. it also made it so i could put newer charger rims on it or something similar. there is also alot more room for bigger tires in the future. ill try to put some pics on here after its all done.
