2 Fuzes-1 with messed up LCD screen,the other with disfunctional audio port

Would I be able to take the LCD screen off the fuze with the jacked up audio port and put it in the sansa fuze with the messed up LCD screen?

You can but you have to be careful.  Its quite hard to put a fuze LCD screen back in and then close it again.  I recommend a really good pair of tweezers :)

how would i do this?
