Advice on changing from stock 14 inch rims and spacing

Sorry! First time on a forum�� It never caught on with me...
Anyhow, yes I have a 1975 Duster.

I would actually like to go for a more "full look" if you that makes sense, basically fill the space without rubbing.
So I don't believe with that want I should go with my current back space?

I do like the ss but I almost like the rallye more because of the simplicity.
And no...no ghetto crappola will be done to my baby!
