St70m lowrider seat

http://www.freewebs.com/daffy3891/hondadax.htm

Does anybody know where i can get a seat for an ST70M it has a proper chopper type seat, not just the banana type.
It was only released in Japan in 1979 (i think)
I seem to have googled the whole world and can't find one.
I tried to put a picture up, but its just given a link, if you want to have a look.
Any help appreciated, cheers.

It's a very hard find indeed.
You should try the japanese Yahoo adverts, or similar auction websites.

Thanks Waynus, i'll keep looking.
