IDK, did not look at it tonight, tried to get the '73 ready to try to take it to Milford Friday.

John was thinking something in the tire (belt or something), but I don't see anything.

I don't think it is bump steer issue as it is an all original suspension / parts and it has the "wabble" on a flat road.

As far as welds breaking, this could still be a factor, but in my inspection it does not appear to be the case (I have not seen anything, but, eyes are only so good). Yes, it is a 67 (weak) k-frame, but this happens on just driving straight, no "performance" driving, I assume (maybe falsely) that all '67 a-bodies did not wander all over the road going straight on smooth level roads?
