17in rims

has anyone put 17 x8 wheels on the rear of 65 valiant? the standard back space is 4.5, ( on the rims I'm looking at.)
17x9?? or is that pushing it,
front....... 17x7? or 8? back space?

I have 8 3/4 rear end, and guess its same width as orig rear end,
seeking larger looking wheel/tire set up.
