Oops, brain fart. "The 1973-later trucks use leaf spring rear suspensions with no panhard bar. 1963-72 1/2 ton trucks use virtually the same axle set ups."
Let me clarify. 1963-72 trucks with coil spring rear suspensions used virtually the same axle set up from 1963-72. This set up uses coil springs, long angled trailing arms, and a panhard bar.
Sorry for any confusion.
