best way to bend(shape) cat whiskers to fit the window opening

on my39 chevy, i converted the doors to one piece door glass i need to make the cat whiskers( the fuzzy strips that are mounted on both sides of the door glass so it does nor rattle when the glass is rolled down) on the end towards the front of the door I need to bend it to curve up.what is the best way to put a bend in it without kinking it? I am not talking about the window "U" channel that fits in the door shell that the edges of the glass goes into when it is rolled up.

What if you find something in the shop with the curveture that you want, clamp it to the workbench, and lightly tap the "cat whiskers" around it till you get the shape you want?:HMMM:

on mine i took my thumb an lighty mashed down on a table pulling my thumb back from the end, until i got the curve that i wanted. then did the other end. jonathan
