Seneca Tire Changing Block(s)

[BahamasFlyer]

In my planning-for-changing a tire eventuality, I’ve read after removing the tire, stick a block of wood under the axle to take pressure off the jack for security.

Rather figure this out now than when pressed.

What height would I want said “axle block” for a Seneca? I'm guessing: 8"? 9"?

Has anyone done this / have a block for a Seneca that's the "perfect" height?
