I was finally piping defrost hoses up to the vents in my dash when I discovered I only had the "cup" for one side. Unable to locate another one readily, I decided to improvise, destroying a perfectly good floor-hose end attachment from my shop vac. I had to use a hacksaw and rotate the neck on it so it pointed the other direction, but now the defrost hose doesn't interfere with the wiper linkage! I started by taping it to the underside of the dash to pre-drill some holes, ran some sheet metal screws in it, drew'er up and attached the defrost hose! I may end up doing this to the other vent just to get the hose away from the wiper linkage! I know it sounds trashy but it works like a champ!

*side note: since the defrost hose is such an odd diameter to find in a material flexible enough to route the way you want it, and without having to order it, I found "carburetor/air cleaner" aluminum hose @ Autozone to work perfectly. $6 for each and you're done.
