The civilian heaters with vacume controls can be adapted to use cables for the stock military function and look. It just takes a little fab work and some cable securing clips, can get them from most lawn mower repair shops. As for the cables I used stock military ones for heat and defrost and they are labelled in white on green correct knobs. I however could not find the fresh air cable. I have a website saved that you can order your cables from and they work very smooth. Much better than 40 year old cables. Google Rays auto air and heat. He makes most every cable needed, they work great and are reasonable in price. I just ordered the fresh air cable from him in the length I needed. I have all stock cables except fresh air. The well oiled nos stock cables still don't work all that well. Good luck.
