WHAT SIZE DRAG RADIAL SS SPRING '65 DART

If you did a proper mini tub job , you are wasting 3 " of room by not moving the springs inboard.
If you do move the springs , a 295-55 X 15 ET Street fits with room to spare.
6 1/2 " back space with a 1/4 " spacer because I couldn't find a 6 " back space rim.
A 5 1/2 " backspace wheel might be about perfect because there is more room from tire to lip than tire to leaf.
But there is a good amount of room regardless.IMG_3039.JPG
