Two questions. Some of the lower, inner door panels I see have a 3" wide strip of carpet along the bottom edge. Is this stock? The available replacement panels don't see to have that feature to glue a strip of carpet to ? 2nd , I'm not seeing any white panels available and I can get some paint to overspray (say a black one), but what SEM color should I use to match the white interior of my 75? THanks.
