I would re read Bob B comments. He has the knowledge. Also, when it comes to '67-'72 GM pickups, generalizations are generally useless. Being year specific makes all the difference in the world, not to mention if U.S. or Canadian build truck. A good truck salesman would recommend leaf springs for heavy duty loads and coils for light duty loads if and when available.
