sheets showing the rear don't show spirals, but Sect 3 sheet 1.00 and sheet 8.00 show the spirals on the front - might even have been that the rears weren't spiral, I can't recall now if that was the case, but I'm sure they more a 'light duty' shock, they were used on most GM cars
NOS shocks that've been well stored should be fine, although that doesn't mean they'll last as long as a modern set, there's some rubber in/on them that may have deteriorated ... OTOH there are folks out there who rebuild them,
M&S Hydraulics might, and check under Chev parts in Hemmings - here's one in Kansas:
