I just bought a 71 Chevelle. While moving the car around my yard I heard a banging/grinding noise from front end. It turns out that the passenger side coil spring is rubbing against the hole in the frame. It's like the spring isn't centered. Is it possible the spring was installed upside down? If not what else could cause this? The bottom of the spring appears to be seated properly, but I can't see the top. There doesn't appear to be any damage to the frame either. Most of the front end parts look new, so I thought that maybe someone just put the spring back in wrong when reassembling everything. Any help is greatly appreciated.
