Re: Another 72 Build Thread

I too think that holes should align regardless of the Assembly line because of the top.
Double wall tops have the nuts in them bolting up through the bedside so from the factory the truck bedside was drilled with holes only.
Single wall tops have holes only bolting down through the top in to captive nuts welded on the the underside of the bed rail.
Since in '72 they used both the double and single walls some Blazers from that year have bedsides drilled for both.
