My son and I created a video on refurbishing and building a new core for the Harrision Heater we picked up which I hope helps anyone interested in adding one to their Jeep. Not exactly the easiest thing to do but it was nice to bring back this old unit to something that actually works.
Looked pretty bad when we got it.
