Where is brake reservoir on 1965 VW?

Open the trunk lid. On the left side of the trunk, up around where the hinge is, you'll see a little plastic tank with a screw-on cap--that's the brake reservoir. That's where it's SUPPOSED to be, but I've seen people move them around for various reasons. I know a few people who've put them behind the spare tire--this way, they won't have to worry about slopping brake fluid on their paint.
