Heater A/C ducting

[MySons280z]

Can someone out there help me find a diagram of the heater/ AC ducting for a 1975 280Z? We stripped our car and now are in the process of reassembly and the heater ducting is a great puzzle. Maybe a picture of the complete heater assembly. Any help would be greatly appreciated.

Hopefully this will help. It doesn't show the right side defoster nozzle and duct but that's pretty much a mirror image of the left one.

Thanks Stephen. That's a helpful diagram.
