i notice your 70 240z has a balance tube where the master vac hose connects to the side. I recently got a balance tube that has only a side port. Im having trouble finding the hose. All the dealers around here say they only make them to go on top of the balance tube. I see yours was tapped on top but mine is not so i cant just plug the side and go on top. Where did u get your hose? Anyone else that run into this mabey u can help too.
thanks,
