Help with Coolant Hose Inside Diameter spec

I need to grab a few feet of generic water hose, but I don't have the car at my location to check the requirement. Hopefully someone on the board can help me out. Car is an early 1967 SPL

The hose that runs to the Thermostat housing / Recovery tank (3/8 ID?)
The short run of hose coming off the water tube. (thinking 1/2 or 5/8 ID?)

See photo

Thanks all

5/16 for the small overflow tubes
1/2" for the larger pipe

Isn't the larger one one of two that are larger at one end than the other?

I believe that is the two hoses coming and going from the heater core / valve. One of which comes off the opposite end of the water pipe. (5/8" one end and 1/2" the other) I only know because of Curtis's "interior redo" thread.
