I found a mint fuel tank on eBay for a good price and also saw plenty of bodywork pieces for cheap.
For the tank side panels, I would highly recommend the following piece. It makes life much easier, as it unites 3 panels into one and it's much easier and quicker to remove (no tabs to break)

also this might be helpful as zx10r tanks don't crash well at all and you wouldn't want it to spring a leak and get your bike torched (as my friend did)
