So I think I may have found a good way to route the left driver side vent ducting to get around the steering column and wiper linkage, but there's a bit of a caveat to it. I think it will route above the instrument cluster in the space in the dash pad. There are even some holes in the dash structure I can tie it off to to make sure it doesn't fall forward into the wipers. The issue is that the hose provided in the kit isn't quite long enough to reach, so I've still got a little figuring to do. I have more than enough hose from the other vents I could probably cut and section, or I might see about making a rigid piece to go in that space above the instrument cluster and cut the hose to go on either side.
