will 3 1/2" offsets fit? Alum slots on 74 Duster?

73abodee- so is your rear rim also a 15x7 or is it wider? I dont really want to go past the wheel well. I told the guy I am interested in the rims. His are 14x7 and 14x9. Yes-15" rims would be better for more brands and maybe better look, but he has 4 almost like new original fenton slots. Never in snow/ salt for 300. Im just hoping these will be what I want. I do want either slots or SS Cragars. I think a 5 spoke with black spokes would look nice but oh well.
