Are there supposed to be clips that hold the headliner bows into the roof in a '67?

I'm in the process of replacing my headliner and there were no clips with the old headlinder, but I'm not sure if this was the original or not.

Now the bows don't want to stay in the "up" position with the new headliner.

I replaced the headliner in my 67 hardtop and there are plastic clips that are mounted in a metal frame in the middle of the roof that the bows push into and slide front to back for when you start streaching out the headliner. the middle clip is stationary

Where do you get the clips?
