Replacing headliner with the windshiled and windows still in..?

[Chrisw]

The car needs a new headliner and every write up I see is the same. Use the clips and the glue. Sounds great, except that I cant fit the clips in at the front and rear because I have my windshield and rear window still in.

Is there a simple work around for this? I assume there is.

Car is a '69 A body coupe.

Thanks in advance!
