S4 body parts on an s5?
 

will s4 body parts (front fender and pass door) fit an s5?

Yes.

you're the man thanks a lot.

one more thing...what about an s4 na tranny in an s5 na?

yes the tranny's will work just fine. Done it a million times.

You might want to gut the door harness out, as the connectors aren't the same when you go to plug them in later, and grab your trim from the S4 stuff too.
