1974 Duster wheels & tire size

Thanks! Yea, they are definitely SBP, and drums. It's a granny mobile, but, with some work will be a nice car for me. Got the 8 1/4 rear to get the bigger bolt pattern so I can get the rims I like, and with the new discs up front, the front and rear will be the same. Thanks again, now I can order wheels and tires, and get the brakes done.
