attempting to rebuild heating system in my 69

[rowleybd]

so this is my first project truck and have gotten really frustrated with what I thought was a simple project. My heater core was leaking, so I ordered everything to rebuild the system....heater core, fan, motor, heater box, rebuild kit for control levers, cables ducts etc.

My frustration is that what I thought would be easily replaced parts don't fit very well. The control cable that goes through the firewall keeps coming off which is inside the heater box and not easy to attach. The defrost/ heater levers do not adjust very well. I found a thread showing which cables go where which was helpful because I did not photograph it before I took it apart. This is a no AC system. I want to make sure that I have the cables routed the right way.

Any help is appreciated!
