Last year I started to replace the old headlines. Due to some water leaks and coloring ( last owner smoking) uninstalling them one by one and at home put on new foam backed leatherette same type as Yngmar suggested
Removed all old material Sanded the old glue and then copied the old leatherette onto the new
Using specific glue to fix the new leatherette to the wood and staples on the back to finish it On YouTube are Many films how to do that.
Now still three to go, one to long to get in the car, and two who are behind the cover of de deck windows. I still have to sort out if the screws and the cover can be removed en installed again without a chance of leaks?
It was also a good moment to replace the spotlights.
