For what was Randy's Bonneville useful?

Randy's car was useful for the whiskey project. Bill wants to use the gas lines to build a still.

"What you're getting at," Randy said slowly, "is that you want me to contribute the gas lines out of my Bonneville." "That's right. The lines out of my car won't give us enough length. And we have to have your lawn roller. You see, first we've got to build a mill to crush the cane. We have to get the juice and boil it down to molasses before we can make whiskey, or for that matter use it as syrup. Balaam, the mule, will walk a circle, a lever harnessed to his back to turn the roller on concrete slabs. That's the mill. That's the way they did it a couple of hundred years ago. I've seen pictures."
