Factory A/C dash louvers

[JimZ]

I am building a 1965 1/2 ton short bed that was not factory air originally. I am installing a Vintage Air Gen IV Magnum. I own a factory center-of-dash louver set and I want to install it in my truck dash where my ashtray currently exists, to give the truck a "factory air" look. I will have to do some cutting to install. I'm looking for info on the dimension and position of the hole to be cut. There are some compound angles on the part so it is not easy to lay it against the dash and mark a hole cut. Anyone have this info? Or, if you have a truck with factory air, would it be too much trouble to remove the louver set and measure a cut dimension and give me a position location between the radio hole and top of dash? (e.g. evenly spaced between the two, or bottom of cut should be 1/4" above radio hole, etc...). Almost two years into this projects which has an LS3/4l80E drive-train. A complete frame-off restoration with powder coated frame and suspension and a lot of other neat things that are slowly eating up the remainder of my life and money. I have included a photo of the louver set. Thanks, JimZ.
