67 AC/Heater

[rico0004]

Hello Everyone,
It's been a minute since i was on here. I bought a AC/Heater hose kit for my 67 LB w/Sm. BW. There were no hoses connected to anything when I got the truck. It was originally a AC truck, but now the compressor,acumalitor assembly, all that, has been deleted. I would like to at some point add the AC back on. My main concern for the time being is to make sure the truck has working heat/defrost. I have the center vent over the radio. The kit came with 4 hoses. I know two of the mid sized(diameter) ones go to each defrost. One larger hose connects to the right side vent, and then to a port on the box. The center vent has the smallest size hose that connects on each side. If i run a peice of larger hose to port on box, place small hose inside connect to one side of center vent. Small hose coming out the other side of vent down into larger peice, connected to drivers side vent. that would leave me with 1 open port on the box? Or run larger peice from port over to dr, side vent, and use the same set up for the center vent? that would leave me with the driver side of the center vent open? I double checked i got the right kit for a 67 w/AC, but i can't figure this out? If anyone can PLEASE give me some advice on this issue? I would GREATLY appreciate it. I know it's something simple, and feel kind of dumb.. lol hopefully these pictures attach?
