I bought a used Z1 from a friend of a friend. When I got it home and hooked it up to test it, I noticed something odd. When the faceplate lowers, there is a white toothed plastic strip that raises and lowers the faceplace. How tight and straight should it be? The unit opens and closes, but it looks like the thing is going to fall off. Should I have it replaced before I install it? How much would it cost and where would I get that fixed?
Thanks,
Scott
