The double wall tops came first, no matter if you had interior cargo panels or not. However problems with sagging prompted the redesign later in the first generation Blazer production run. I believe the single wall tops began showing up in 71 and 72, but not all 71 and 72 Blazers got them, as there was double wall inventory to use up before the redesign in 1973. If you notice, all 1973 and newer Blazers have single wall tops with nearly identical construction as those for the first generation Blazers.
