The Ravager. A film from 1971 about an American GI who was in Vietnam and came home and became a killer. Looking for the DVD. It was available from TCM back in 2008 but I can't find it now. Can anyone help? Thanks.

(Everything I have found shows it as 1970) I've read that it has been purchased from Something Weird Video in the past... (fyi looks like kind of a raunchy site) don't know if it is still available.
