I have a 67 Firebird with a Wayne Due C4 subframe. The subframe was installed when I got the car. The sway bar that is on it is too narrow and rubs the outside of the frame rails. Does anyone know what sway bar is supposed to go on that subframe? Any advice is greatly appreciated.
Can you post pictures of both ends? I had a similar issue and found the bar was not staying centered. I welded a pair of rings on the bar to act as bushing stops to keep the bar from creeping left and right.
