70 Dart Swinger with 275/60/15 E/T drag

Hi
I would like to ask if I can fit a Mickey Thompson ET-Drag-R 275/60/15 in a 70 Swinger without touching the 1/4's. It's a nice 340 car and would really not want to cut the car. Can it be done with proper offset?
Would like to hear from owners that had this dilema and what was the results.
Thanks
