I saw that you had bought that gem on the weekend when Manny
@70 Sport Suburban informed me your post on Facebook displaying it to the world. GJ4 is one of my favorite colors. You surely scored!
I was hoping you might join this site since I am a fan of those cars and still have 4 left myself including the Newport joint venture that Ayilar and I have (I sold my 1971 Imperial sunroof car to a friend in Australia who proceeded to restore it completely).
The 1971 Imperial restoration was highlighted in this former post:
My 1971 Imperial Factory Sunroof 2 Door Coupe
I have one 1971 Chrysler New Yorker sunroof car myself and it too is low miles (38K I recall) and is Lemon Twist with a white vinyl top and white bucket seat interior like yours and a U code 440HP. I am the car's first titled owner since it was previously ordered and owned by a dealer owner named Phil Rauch in Burbank California who never registered it in his name and always drove it around on a dealer plate. According to his son, it was his favorite car of all time.
My other two are both Chrysler 300s - one is Tahitian Walnut and the other is Aztec Gold (a U code 440HP car).
Welcome to the site and as Ayilar mentioned, there are plenty resources here to help you with your New Yorker. By the way, does your sunroof currently work OK?
