Did all 428 SCJ Mustangs equipped with "V" code 3.91:1 rear end gears come with a Ford "Traction-Lok" differential?

Starting in 1969 Ford began offering an optional 3.91:1 gear ratio that used Ford's Traction-Lok differential, which used a clutch pack for quiet, streetable rear wheel locking under hard acceleration in a straight line. Order this option and you also got a 428 SCJ engine!
