Can I get Hindi audio track for Shawshank Redemption?

I have the movie with English audio track. Can i get audio Track for
the same movie in Hindi (only audio track not complete movie)? If so,
from where can i download it?
Can you please assist me (if it gets) how to add it to the existing
.avi video? (so that while playing the movie, it will be played as
dubbed Hindi version)
