I have the 3 twist knob/cable control heater box. It needs foam. It was the one out of my personal car. All works, it just needs re foamed and put back in. It takes about 2 hours for me to clean and tape/foam the doors, so I bought another box for my personal car and did it before I took the car apart so the long job of the heater box would not be as long. I had around 125.00 in the box I bought, that is what I will ask for this one. Let me know, Lucas><>
