While trying to fix a vacuum leak today on 82 300SD I discovered that both of the footwell flaps are broken. The shafts with the gears on them are sheared, are the flaps and gears available? Also how much of the dash and heatrer box must be removed to access them? Of course the vacuum switches for the footwell and fresh air flaps are leaking as well but I think that new diaphrams are available to repair these.
