I see you chose almost the same heater as me. I went with the 3 vent unit. 2 for heat and one for defroster due to our ocean front weather. I used part of a 3m 777 spray glue cap as a spacer and some inexpensive vents from Jegs. They fit right in the heater outlets on mine. I will say these new heaters will drive you right out of the cab they put out so much heat. Heater block valve a must. Remember this is a military vehicle so its field expedient in nature.
