adding another fly in ointment; fortunately both My V.N. built 71's have their build sheets intact, one being a pretty early build (08) and the other later on (02) and both show the exact same two letter codes in their respective box's for the hoses which correlate back to that 3115 number for the upper....not to mention the photo I posted earlier of the 04 built car with what looks to be its as-built-with 3115 upper hose.....in all these examples it appears that
NS is correct for at least 1971 and maybe a bit beyond that. ....
