How can I separate the wheel hubs from the drums?

Hello guys and greetings from Switzerland!
As the title says, I would like to know how to separate the wheel hubs from the front drums.
1968 Valiant 9" Drum Brakes.
The drums tend towards the end and I bought two new ones on rockauto (without bolts or hubs).
Is there a trick or is it best to buy new hubs? (If so, where?) :)
