67-69 Dart...275/60/15 drag radials...how low is your stance?
That's a great look!! Now, clean up that garage dammit!
I have 275's on an 8.5 C/L wheel 4.875 BS on my 70. Pretty similar wheelhouse, etc. I only moved the spring over with offset boxes. The rear is shortened a little as well. Using frame relo boxes you'll have a bit more room than I have. I had to trim the fender lip.
