I dug out my defroster vents and was a little surprised to see that they were different, both in length and the diameter of the nozzle. The longer one has a nozzle that's 2" dia., and the shorter one has a nozzle that is 1-3/4" +/- with a rubber ring on it to bring it up to 2". I don't recall which side they came from but I'm guessing that the shorter one was on the left side to clear the wiper arms. You can see from the cobwebs and bugs inside that they're original. The nozzles on my recirculating heater are different sizes as well, with the same type of rubber ring on the smaller nozzle. The smaller nozzle on the heater points toward the driver's side. Hope that helps.
