Nearside trim removal from A plillar

[owen1]

Hi All
I am fitting a DAB radio to my 1994 993 convertible and need to install a DAB aerial, probably a stick on one to the nearside of the windscreen.

As this will mean earthing it on the A pillar I will have to remove the trim on the pillar. Can anyone offer any tips please so that I do the least amount of damage?

I have read various threads which suggest that it might be glued on.

Thanks in advance for any help.
Owen
