73 duster 17" or 18" wheels ?

Thanks for all the information and help. What I am leaning toward for my 73 Duster are some Cragar 500's, either chrome or grey. Will 17x8 with 4.5"BS fit on front and rear or will I need to go witha 17x8 w/ +6 offset / 4.25 BS? Also, any recommendations on tire sizes if these wheels will work or not. I prefer to have the deepest wheel face as possible and width without spacers.

Hopefully this additional information will help to understand what I'm looking for. I have seen a lot of Duster with 17" wheels (Welds, centerlines, etc...)on FABO, so if you got photos of your setup in this application it would be helpful.
