I am not sure why the seller is referring to the hose as NOS . https://www.ebay.com/itm/NOS-1967-MUSTANG-SHELBY-GT500-390-P-S-CONTROL-VALVE-TO-PRESSURE-HOSE-C7ZZ-3494-A/174174513205 The cracked rubber ,substantial corrosion on metal fittings and tubing,and what appears as dirt and grease all over are more the definition of used not NOS (New Old Stock). He might get some push back from a un informed buyer when they discover it is not new unused as described. Buyer beware.
Bob,
NOS = Nasty Old Stuff ?
