spark plug wires
GPS is still in auto parts marketing business and is a unit or Standard Motor Products ... but no GPS wires.
There's always the possibility of NOS sp wire sets on fleabay etc but you'd need the set/part # and that's not shown in GPS eCatalog
Maybe a longstanding parts store near you would archive (stacked in a dusty box out back) obsolete countermans' catalogs.

I just installed this set. They were all a couple of inches longer than OEM which wasn't an issue.
