67 headliner
Yes you can put the headliner in without taking the widows out but it isn't correct.
There are teeth designed to hold the headliner, one seen just below the clip and another to the right of that.
I'd be worried that the headliner would come untucked or not be able to get the wrinkles out installing it.
Maybe if you get enough glue on it, but how tight will you be able to get it.
