17x8 wheels on a 68 Cuda Fastback

What size tires do you want to run? I think the outside edge is might stick out too much at the center top. Pretty sure going to have to move/fold/cut the front bottom corner fender lip.

I've mocked up 275/40/17 on 17x8 with ?2000 mustang rims with around 5.5" backpacking. Little narrow rim for that tire.
