I just looked at the picture for the link I sent, they do look grey, but are in fact black exactly like the ones you pictured. maybe it is a protective sheeting or something in the picture?
Ahh, ok.
I got them on the glass with the retainers/guides. Slid it into the vent window frame and it is toooooo tight and hard to slide. Did you use some powder graphite or something to make it slide easier?? Looks like it is rubbing the felt off near the bottom!
