There are 2 items for sale here.
The first is an excellent used full set of standard green 1970 door panels and rear panels.
These are correct for Darts whose VIN numbers begin with LL23 (Swinger) and LM23 (Swinger 340). $150 plus the ride
The second item is a set of door panels just like those above, but these are not in as good a shape, but certainly very presentable. $60 plus the ride.
