Welcome to the forum.
I made my own from 0.047in dia steel wire. I cut the pieces to length, then bent them using a home made fixture in an arbor press. Installing was an all day plus task using the existing holes on the shields and new rubber. Good luck.

I put down the wire diameter as 0.032inch. The diameter of the replacement staples I've ordered were 0.062inch. I think that was the size Ford used for replacements and the aftermarket "copied" what Ford did. It's wrong.
One more point, I measured the staples on a 66 San Jose car. Measure yours. Also check the "form factor" of the staple, round or a rectangle profile. The rectangular ones may have a diagonal slant to make a point for penetration.
