Headliner question

I pulled the original headliner out of my 69 Dart several years ago and I'm getting ready to install a new one soon. Can someone tell me how many of the wire hooks (as shown in the picture) there should have been attached to the front/rear headliner bows? I thought there were three when I took the old headliner out but now I can only find two of them so I am wondering if there were only two and not three as I thought. Also, however many of them there are supposed to be, could you tell me how many hook to the front and rear bows?
