Mopar Tim, what year is your Dart? I've looked at these, but not sure if '75 Plymouth Scamp is 108" or 111"? I've read both. I don't trust my measuring skills!
1969 Dart, I measured it, it is 111 inches. Convertible. Just face front wheels straight ahead, and measure with a tape measure, from hub center to hub center.
The difference between 108 and 111 is very noticeable, you can tell the difference readily.
