Headliner bows

Ok I got a 68 barracuda notch back the headliner was out when I got it and a couple bows don't have paint on them can anybody tell me how to figure them out? I thought about just putting them in without the headliner but a couple are pretty close to being the same shape and length and I seen some from a 67 and the colors are different also any body got pics of where the spring hooks snap into its been about 20 years since my last one
Thanks in advance
