The vent outlets won't work how I want them to, partially because the glove box "box" is in the way by about 3/4". I suppose I could move the heater down a bit to clear the box but I originally had it mounted low and ended up moving it up and out of sight.

So my answer to my slight problem is to build a new face plate for the heater and redirect the outlets. I need to provide heat for the floor of the passenger, the floor of the driver, and both defrost vents.

I hope this works!
