Mummy hose

question: the z-store doesn't have the PCV hose for 70 240z, but they do have it for 71-72. they look very similar, does anybody know what the difference is between the two?

I am assuming the difference is an extra bend to accommodate the hot air tube from the exhaust to the air box that didn't exist in 1970.

I am also guessing (?) that this extra bend would take the hose further from the manifold and provide a bit more heat protection.

I hope someone in the know will confirm or correct my assumptions - thanks.
