Looking at picking up a NOS 13lb cap and was wanting to make sure that the 13lb's was ok for a 4 core radiator. If not, what is the correct one?

Here's the one I liked. Thanks for reading.

No difference with a 4-row, just use whatever the spec is for your truck. If you have added a coolant recovery tank, you'll need a cap for a sealed system. IIRC, my '72 calls for a 15# cap and I'm using a 16#.
