Just wanted to get your guys opinion on what rim size I should use on my 66 300. I'm running steel 15" wheels on it now... But I have 14" steel rims that came with the car. I'm not sure if that's what came factory or not? The hubcaps I have for the car will fit the 14" rims. I also have a set of Chrysler dog dish caps that will fit either 14" or 15". Im gonna be buying new white walls for the car next month. What's your guys' thoughts?
