Hi Mopar(ts) Lovers,

I'm currently rebuilding my a/c box. It was broken completely at the fresh air door. Rebuilt everything and I'm very satisfied so far, but need to know where exactly I have to drill the hole for the fresh air door helper spring. I've found the attached picture on DMT's instructions (got the new Foam Resto Kit from them) and noticed that I've found such a spring.
As the damage went through the hole, where it is hold in the box, I don't know where exactly I have to drill the hole now.

Can someone of you please measure it? I like to give the spring the right position, so that it can help as it was designed.

Many thanks
Thomas
