Duster Rear Window Louvers

i love that 70s look with all the factory scoops, spoilers, RWL tires , rallyes with trim rings, hood pins, dual body color sport mirrors , all the factory blackout treatments and stripe options and CID callouts, badges , factory hood tachs, buckets, consoles, high impact colors, tuff wheels, four speeds, chrome exhaust tips and the only way it could get any better ,would be LOUVERS. ya, im old school, thats why i love this stuff....i cant stop looking at the petty blue sport with the black louvers, that thing looks sick. im going to have to make some cardboard rear louvers for mine
