I believe the system with the Outdoorking shop is that if the part is not listed you can PM Bruce and he will see if he can get them through a distributor. If he can get them, he will add them to the list.
Other than that I think you would probably need to find a US source who is willing to mail the parts overseas. In my experience some are and some aren't, but you can usually find one who is. If they are not available from any source, bushes can usually be turned up on a lathe quite easily.
