JE will, I am sure, be only too happy to source anything Kyosho for you (along with most other stuff too of course but since you can't get better than the mighty K' that won't interest you .. lol)
I've yet to see anything I've looked for in the ranges they stock at significantly better prices anywhere and they seem to be happy to get the 'unusual' parts too.
I don't think you will be disappointed by either tha car or the on-going service from JE
Have fun
