Parking lock cable

1965 300.
Question from someone that has not done this before. Removed the 727 in order to change some seals and go through it.
The issue is the parking lock cable, first are you suposed to get it out from the housing cover?
I have removed the cover and loosened the clamp bolt and tapped it both lightly and later on a little harder. But the cable seems to be totally stuck in the cover no matter the position of the clamp bolt. View attachment 376501 View attachment 376502
