16's on a 65 Barracuda?

Down to $ on wheels and agree with abodyjoe that 17's are the way to go. I need to know if fender wells (inside edges and outside edges) on a Dart are the same as the ones on the same year (65) Barracuda. I see alot of info on Darts but very few on 64,65,&66 Barracudas. I have K/H factory Disc., SBP all around,7 1/4 factory rear. I want to have tires the same front and rear to be able to rotate ( D.D. you know) and a little lower stance but not in the Weeds. I would like 8's all the way around and a Tall enough Tire to fill up the Fenderwell but not over power the look of the Car. I have a Firm Feel Quick Ratio power steering Box , upper tubular Firm Feel "A "arms and full rebuild poly kit, 340 torsion Bars and Gas Adjust Shocks all around. I hate to over analize somthing this simple to some of you but I am lost.....any constructive input welcome. Thanks Tim :banghead:
