PCV Clarification

[cortcomp]

I've been researching the PCV system on my truck (california emissions '66)

From what i read and how it was hooked up, it was basically the rear vent port to the air cleaner, and then the PCV in the filler tube to the manifold, and a non-vented cap on the oil fill.

I am going to somewhat re-create that (with a rear vent to the drivers side and putting my own connection into the air cleaner with flame arrester, since my passenger side oriented vent tube was mangled and i don't need it's A.I.R. system bracket, and my air cleaner doesn't have any fittings yet.)

In the pic below, basically the bottom setup is what i think i'm aiming for. My questions are (and sorry if it's been covered, haven't found answers searching):

1) In the diagram, they don't show a PCV but show a metered orifice. My fill tube has the threaded port for the PCV valve and i have one in there. Assuming that the PCV acts as the orfice and i can just connect the rubber line from it to manifold vacuum?

2) I see a lot of guys going the other way, rear vent to pcv to vacuum, and the front with the vented filler cap (basically top in the pic below). Does it matter? I have the parts for the second option and it is kind of closer to original for my truck.
