Early A wiper assembly question

You could cut your own. A MAC gasket cutter set would do the trick. A leather punch set would work as well. Most craft/hobby stores should sell one.View attachment 1715237767
Thanks Toolman Mike.
I’m going to try directly to a fabric store. The material hole punch set is nice but will collect lots of dust in my shop. I figured since this was the build years ago somebody reproduced this part. Before the wipers made a lot of noise at this location in my car.
Being under the dash it was noisy.
Got to fix that. Over $35k into this little Barracuda now what’s $20 more.
