'72 Duster Brake Line Question............

[Eat My Dust-er]

I'm wondering if anyone can tell me where the front passenger brake line connects to on the proportioning valve on a '72 Duster? Does it connect on the side towards the firewall or on the side towards the radiator?

Just looked at mine real quick and it looks like the passenger side is on the side towards the firewall.
