Price of 8.75 option for 1967 barracuda

Thanks for the help and information,like I said have always wonderd how Mopar made the choices in putting the weak 7.25 in,so even with an automatic you could get a 8.75. But I'm quessing since I had the 6.95/14 narrow tires and you had the wider red streak,that also gave you the 14 5.5 inch rim. I had the 14 4.5 inch rim,which maybe they knew the wider tires would kill the spider gears is why you had the 8.75 open rear. I believe Mopar though with automatic and narrow tires you would spin the tires before stressing the spiders. But I used a bolt adapted to put the "G" 15 inch tires and the spiders didn't stand a chance.
