Grant Tuff Wheel in my 67 Dart...
I did not use the extention on mine. The turn signal lever hit the wheel on mine. I just bent it a little out of the way. On thing though is with out it the wheel is low to the seat and may hit your legs with out it. I got the extention but did not use it. My legs did not hit and I did not like the way it looked. Here is a pic.
