Quick Heater hose size question

[Weak440]

I have a '74 Duster that I am going to flush the cooling system on. I am going to replace my heater core hoses before I am all done with it.

I was wondering if anyone knew what size they are? I think it uses two different sizes? 3/4" and 5/8" OR a 5/8" and a 1/2"?

Take the hoses to the auto parts store and they will match them up with the new ones.

5/8 and 1/2. The bypass is bigger.
