Vented Radiator Cap / Partial Pressure Coolant System...

I've got a 1970 Plymouth (Valiant) service manual. It's the closest thing I have to my 1972 Plymouth (Valiant) Scamp. And it states to use a 16 psi vented cap. And that's what I will use. Which is what the Summit part number is.

Juz' sayin, you can download a 72 and other manuals free from MyMopar. That manual and several others on there came from the guys right here

I don't see that the cap matters. Pressure, yes, but "partial or full" no
