The only way I know is to cut the lip off the rubbers inside the car about 20mm up from the edge as the rubber is too hard [as in hardness] to take out without damaging the glass..
My Son & Wife are installing a headliner today in My 1968 AutoStick Beetle. They have done 5 others... Better than Me having to start learning on how to do it.. I was intending to do it, as I have done everything else on the restoration Myself apart from the engine overhaul.. and brazing 2 spots of rust up under a window rubber.
Be sure to use Plenty of Fish oil to stop any rust happening again. Spray inside the roof side cavities, heater channels, under the front & rear window rubbers and around the rear window from the inside, where late beetles do rust.. inside the doors and under the engine lid and bonnet rubber seals... Best of Luck.. I have used over 4 liters of Fish oil on MY car.. and I have NOT done underneath the car as yet, but as We have NO chemicals put on winter roads, I have just painted under the chassis...
