N600 Headliner Removal

[gotmonth]

Hello group, I am ready to send my '72 N600 to paint and need to get the headliner out.  I remember seeing in our group some time ago info on safe removal.  Someone also posted some photos of a tool they built to make this easier. I see the factory shop manual tool and instructions but of course they are made of unobtainium. Thank you, Alan
