iPod Parts to rebuild iPod 4th gen

[kge420]

As a favor to a friend I'm restoring his iPod gen 4, 40 gb. I have installed a new battery and hdd. I ordered a new front faceplate off ebay. I am looking for a new back plate and click wheel. Does anyone have a source for these?
Thanks

Many quality parts can be ordered from here: http://www.ifixit.com/Store/iPod/iPod-4th-Gen-40-GB?display=list

I recommend iFixit parts as I haven't had one go bad yet! Also, their repair guides are fantastic.
