Radiator Hoses

See attached parts book scan. It indicates that there is no difference between early and late 260Z radiator top hoses, but there are differences on the bottom hose (even ignoring the air conditioning option).

Early 260 i believe uses a hose similar to the 240 but slightly longer at the rad outlet stub end,
because of a larger radiator but with the rad outlet stub still pointing upwards.

later 260 the outlet stub is horizontal, so hose has 90 degree bend at the bottom.

The upper part of the bottom hose, where it goes into the block is slightly different as well on later 260,
it has more 'curve' to it, to help avoid hitting the AC pump, although this probably only relevant
to US sourced cars i.e. 280z, it still fits fine, as i have one on my car :)
