If you find any you are more than likely going having to re-chrome them but I can suggest a few alternatives.
RM100A forks are the same and you can use the TF125/185 forks and wheel (they are in-line axle type not leading axle type like the TS185ER and are 33mm not 30mm) as for an airbox it may be simpler to build your own as when they do show up on eBay they are usually incomplete or outrageously expensive if complete.
