Hemi Charger rear suspension

OK....I finally found it in a March '99 High Performance Mopar magazine.
It was called "Hemi Suspension" on the order sheets, and was standard on Hemi cars, and was optional on 383 and 440 automatic cars with HD suspension or optional Axle Package.
They had 5 leaves plus 2 half leaves added to the right rear.....the half leaves faced forwards, and none after the saddle.
