How to remove the vinyl roof trim from a 1966 barracuda

[68 dart conv]

Hello Team I need your help with how to remove the trim and not damage it for the sides and over the top of the roof? My head line needs to be replaced so I can cut holes in it if needed.
Also if you have any photos of the plastic mounting parts or who to get them from?
Thanks for your support
Dan
