Your best bet is kg. If they don't have it your just better off going to blockbuster.
Blockbuster doesn't have them otherwise I would have went there, that is why i am looking on torrents
Actually Cinemageddon is the best place to look for 70's and 80's Westerns .
Desperado: Avalanche at Devil's Ridge is listed there - unfortunately with no seeds but as it's a relatively new torrent a reseed request might work.
thank you if you find the other movies in the series let me know. Thank you again
