The voltage isn't the issue. The output impedance of the head unit could be but probably isn't an issue.

You could use the correct value and use a screwdriver to adjust the gain. In my opinion, that would be the best option if you can't find the original pots.

What wrong with the originals? If the back has popped out, it can be popped back it. If they're noisy, they can generally be cleaned.

The preamp output impedance of the head unit is 50 ohms.

The legs are broke off one pot and one has popped apart.

In my opinion, it's better to have an amp look a bit different and remain original, electronically. It's your amp so you'll have to make the decision.

With a 50 ohm output impedance (assuming that the impedance is flat across the audio spectrum), the 10k pots won't make a difference.

They are actually 5k pots, I guess I will try them and see.

I was referring to the replacement from mouser that I posted. 5k would work for testing.
