Headliner bow removal

Did some searching & couldn't find anything. What's the easiest way to take the headliner bows out of a 1970 Swinger? I'm trying to take the headliner out with the bows still in it. Do you bend the clips down or take the clips out or something? The bows don't seem to move very easy. Thanks guys, if it wasn't for this site I would be screwed.
