Do you happen to have the original packaging for the felts? There has been at least four to five different vendors in the past 25 years that I know of. The felts can be very accurate to barely usable. That is why I am asking for if you bought the rubber style that acts as a wiper blade and try to use the correct extrusion style, then they will not match up to the quarter felts and may not work properly with the inner felts as supplied in the kit. If you can post a picture of what you have, then it may be possible to help you with what you have. Just a close up of the profile would be all that would be needed. I will send you a private message.
