Shown below is a pile of factory spark plug wires from my 85 442. They only had about 25K miles on them when I pulled them and swapped them out for new ACDelco ones. I kept them for some reason. They're a bit different than the Delco replacements in the plug boot is a bit different and not as thick, as well as no manufacture date, only a cylinder position number on them. Did an ohm check on them and they're all good. Might clean them up and reuse them. I used them to modify an NOS ACDelco set from another V8 I got dirt cheap to the same size set as this one.
Also, never noticed this before either, the factory distributor boot retainer has cylinder position number on it as well. The NOS ones do not have the numbers. Strange. Early versions may have, but I got my NOS ones in the early 90s, so...
Original factory unit on left, NOS retainer on right.
Anyway, thought I'd share. Not too often you find original equipment that are typically considered consumables.
