I figured it out, when my jack came in today. The winch attachment sticks out to 45 inched from the base, but is easily repositioned to not stick past the standard bar. The bar is 41.5 inches from the base, and the handle 41 inches from the base. I have 40 inches of width in the back of the Golf... but it will be trivial to cut off the extra inch and a half from the main bar, and lose an inch off the handle. I'll end up with a custom 40 inch jack, that will be a regular desert camping addition.
