Doug, you are correct, NOS = never used, BUT what assumptions did I use ? the part clearly says HOLLEY, not Autolite,as an original, Ford tagged,part would have for I.D.. They are service parts, direct from Holley, not OEM, BJ /BK pieces, and will work fine, no need to take them off the market... I guess I should not try to supply correct information to people that have all the answers already
