NPD says maybe both white, maybe both yellow, maybe one yellow and one white. Apparently there's a difference between the a/c cars and the non a/c. Thanks is advance.

I am pretty sure either is actually correct. If you have the Mannel book, it may reference it there. My '66 with factory a/c has white stripes on both hoses.
