Headliner help

I've been known to go to much effort to help members.
My problem is I dont have a similar car here.
I can tell you the mfgts didn't change stamping dies unless absolutely necessary.
If you have afabric headliner, unfold it and count the bow sleeves. Now look at the roof rail member for the same number of square impreesions in the metal. A little comparion measuring betwen bow sleeves hould provide a clue.
keep in mind that the bow doesn't stay in the sleev all the way to the clipped ends anyway. The sleeves get cut open to release the last few inches of the bow.
