If I can guess correctly, it seems that the OP wants to replace the "old"
style sagging bags of rubber grit with the "new" style (though still old)
molded visors of labor models.

I had the former in my 83 vanagon, and tried everything, including making
new cardboard inserts for them to filling them with expanding foam clamped
between two boards for flatness. NOTHING came close to the later style.
Trouble is, if you have a Westy or really early van without the molded
overhead, you will snap off the plastic clip towers as soon as you try to
clip the much fatter later visors to them. I solved the problem several
years ago by taking Bus Depot visor clip towers and sawing the bottom off
of one and the top off another and epoxied the two together. This makes
them taller, tall enough to accommodate the fatter later model visor, which
hold up well and allow you to wire in the lighted mirror if you wish. But
mainly, it allows you to use more readily available good-quality visors, as
probably zero of the older models are in good shape by now.
