Headliner "Hold-down" Strips

[Hawkeye's-911T]

Hi All
I am about to install a new headliner in a 1970 coupe. I would like to find a source and or a part no. for these strips:

They appear to be constructed from a type of cardboard/paper material.
Dims: 29mm (1 1/8") wide x 2.4mm (3/32") thick x 280mm (11") long. They are located at the base of
the "C" pillar where the headliner transitions to a contact area under the parcel shelf cover They were
originally held in place by spiral nails (?). I believe some form of sheet metal screw as a viable replacement
for the nails would be a logical upgrade.

Thanks in advance.
Cheers
JB

I just made some of these today out of thick brown posterboard…please post if you find a source

Soak them in warm water until saturated, lay on a flat surface, flatten them, put weights on them until dry.

Nothing better than original parts.
