I use just a good flat washer on my flex fan. What You mit want to use is The washer/Shim moroso sells. They come in a kit of different thicknesses.I'd use the thicker one If you can. this way you won't crimp it in anyway.
(moroso Pully shim Kit 64035) There is 3 in the Kit Now That I am looking at a kit i have here You should be able to use one of the thiner ones.
(If?? I knew what I did with the Open Kit I'd Just send you one)
God doesn't like ugly.
