14X5.5's on my 66. It had a #368 "Dart Rallye Package" which included HD rear springs, HD torsion bars, Front sway bar, 6.95x14" Blue Streak Tires, and wide rims.
Thanks! So the wheel cover in your first picture is original? Where do you find if you have the #368 package, is that part of the certicard or VIN or on a build sheet, which I don't have. Like your wheel choice BTW, what is your paint color, looks similar to mine AA1 = Silver Metallic
