that's 73/74 B body bottle ( or at least does look it is ), mounts on passenger side of radiator core support. The lower part fist just RIGHT ON frame rail

EDITING:

no, is not, pretty much similar, but the neck is unexistant on 73/74, is simply flat top and then directly the cap. This one has a top neck
