I have the frame conectors from US CAR TOOL and the fit on my car was perfect ! I do have a 71 Challenger, not a 70 But I also had both sides of the front floor replaced woth reproduction pans and they still fit great. When Goodmark sent out the first run of fenders for the Challenger , one of thew had the headlamp buckets welded in wrong. I call them up and they had it picked up via UPS freight 2 hours later. You just gotta give venders a chance to make it rite.
