New Wheels and Tires for '72 Valiant!

So I should be able to fit 235-60-15's on mine too right 74 Valiant? I dug into the wheel and tire threads....but I guess I was unsure which Mopars compared to mine so that I would know how big of rim/tire I could fit? I did find one thread on a '73 Valiant 4 door which can't be too different if at all. The people that replied stated to fit 235-60-15 or 245-60-15 in the rear, he would need a 15X7 w/4.25 or 4.5" backspacing....can I assume that this applies to me as well? If it does work with my '72 Valiant, then I am off to get quotes on tires and rims!!! Woohoo, if not, someone please chime in and help me out, I need to get my car looking hot for summer! I will probably go with 205-60-15's in the front, what size rim for those though? As you can tell, I am not expert with this tire and rim stuff... Thanks in advance.
