I have a 73 that the heater box was taken out of. I purchased a used complete heater box that was removed for a rebuild a few months ago. On all broncos I can find the heater core hose attachments stick through the two holes in the passenger floorboard/firewall side by side. On the heater box that I purchased the heater core hose ends are vertically configured. Did they change between certain years or is this possibly an after market piece?
