posi , sway bar discs to or 10'' drums ? many moons ago i had my first 69 gts (sport) 340 10'' drums on it power , but still drums . so i got with a guy that have a 69 dart /6 auto on da tree 4dr sed in his yard , needed body stuff that it had , he was going to scrap it . i talked him into bring it by my place before it got crashed . hanged the front sheet metal bumpers taillites grille , you get the pic , right . i need a spare for mine , so i crack off the lug nuts , and low n behold , k/h disc braked on a manual master . needless to saw it could not roll any more , lol . he was pissed off , but money eased that over . never checked , it could have had a posi 7 1/4 in it as well . back to your great find , have you decoded it yet ? great car enjoy it .
