I have a 403fb with 3 slides. 2007. The black slide seals are dry rotting and I want to replace them. Can someone tell me what I need to order? Are they a "d" seal? Please, if you will, give me a brief explanation on how to replace the slide "wiper" as well. As far as I can see, the "d" measurement is 1 1/4" and the wiper part is 2 5/8" wide. Does the wiper go under the metal bracket?
Any help would be appreciated.
