as Brad points out, regardless if there is/was any meaning to the markings found under the hoods of
some trucks for the assembly line workers, they're of NO "significance to restorers", us, or a museum, there is no "numbers matching" game in old Chevy trucks .... and I'd say that particular mark has nothing to do with the assembly line [and your link has doubled http, doesn't work -
here it is]
