5th Gen iPod classic HardDrive/screen Upgrade?

I have a 30gb 5th gen video (classic)

I have a single platter 160gb Hard drive for a 7th generation classic.

(Bought a new ipod classic and a few months later, the logic board goes bad. Apple wouldn't replace it)

I have already swapped the Battery from the 7th gen into the 5th and it now lasts much longer!

But can I use the Hard Drive in the 5th gen?

What about the screen?

I also have an engraved back, Can I use it?

What about the metal faceplate?

I have read several places that the faceplate and screens along with the drive are interchangeable but im not sure.

EDIT:

I already swapped the drives once and everything went smoothly, I formatted the 160gb drive and started to sync my music and my luck ran out when the power went out.

The ipod then crashed and said I had to restore with iTunes.

But no computers will recognise it.

I put the old 30gb drive into it and it works fine, like nothing happen.

I have a ZiF-to-USB adapter so I am guessing I need to force format the 160gb HardDrive and try again?
