Can new window fuzzies be pre broke in???

I got some new Top Cat window fuzzies for my 72 Swinger, I put both inner & outer ones on my passage door & had a hard time getting my window up & down, so I just took them back off and put my old ones back on.... Wear their not curled up like the old ones, is their any way you could pre curl before you put them on, anybody got any crazy tricks that work?

Steel if you got them to curl up like the old ones, would they let the window work ok, because I see they are just a small hair thicker?
