68 hp manifolds in a B body

I know they will fit the heads Craig I am not sure about routing the pipes and what kind of bends are going to be needed, I don't want them hitting the frame or a half inch off the inner fenders,,,etc
I posted on the FBBO board as well and searched every site I know of, but seems no one has used these on a 71/74 Charger / Runner...which is why I am abit worried, don't want to layout the $400 if they won't work.
