As you can see, a 1956 Cadillac has it mounted vertical and up near the radiator. A lot better arrangement than putting the damn thing under the steering column, that's for sure. At least it gets it away from the heat, which I'm thinking is a good point towards failure.

Also, take a look at this website:http://caddydaddy577.corecommerce.com/1956-1957-1958-Cadillac-Bendix-Treadle-Vac-Master-Cylinder-Rebuild-Kit-FREE-shipping-in-the-USA-p3054.html

And the picture they show for their rebuild kit:



Makes me wonder if people are selling a generic BTV rebuild kit.

And on another note, I'm thinking that the incorrect gasket sealing off that port is the reason why people are finding fluid in the vacuum side of the unit, it has no where to go and the pressure of the return stroke is pushing it past the rear seal and into the booster side of the unit.
