Where do the coat hanger hooks go?

[bajanick]

OK, rookie mistake, I just installed a new headliner in my 65 Dart GT and forgot to mark the location of the coat hanger mounts. Can anyone with a similar car give me a measurement from the edge of the rear glass to the center of the coat hook screw before I start poking holes in my brand new headliner.( which came out really well!)
Thanks
