17 help!!

Hello I know its a beating drum. But rebuilding a 71 Duster Twister. I've seen some pics of 17x7s front and 17x8s rear. Was looking at some Nitto wheels or Rallys. Car is all stock suspension wise. Converted to disc up front off a 73. 4.5 in bolt pattern. 8 3/4 rear end. Was also wondering about 8s up front also. So I need ALOT of intel from you guys. What is the max width and bs on the front and rear I can go tire sizes ect. Pics and specs GREATLY APPRECIATED!

Nitto 245/45R17 (on 17x7) front
Nitto 255/50R17 (on 17x8) rear

No fenders on, but I thought I would send you these pics anyways...
