Upgrading Rims and Wheels for a 1968 Dart GTS

Not on my car now, but I had 15"x7" Cragars with 4.25" back spacing, with 225/60R15 tires on all 4 corners of my '69 GTS. They will work and nothing will rub anywhere. Huge improvement over the stock sizes. (But there are a few people on here that will tell you that you must put 18" wheels on it. I'm sure him/they will be chiming in soon.)
