May not be any use to you but Asiana have a 767... I think it is a 767-200. What do you actually need?
I am not sure if they sell 3rd party time either...Alteon does their training though.
There must be 76's in Japan but they would be airline owned and doubt they sell time. Could Seoul be any use to you? I could put you in touch with Alteon if you wish.
Best!
