I have a 67. And the entire front end seems to creak and move when driving under some what hard conditions. Although I have had the entire front end suspention worked on, including New Ball joints, bushing and sway bar. There seems to be some movement in the front end. Upon inspection, I noticed there is not much of a frame and support foundation under the older stangs. Any one ever have this problem. And if so, what can I do to fix it..
