66 Dart Owners thread

I run 15x7 weld wheels with 4.5 inches back spacing and 255/60/15 m/t drag radials on my 66 Dart. The springs and wheel tubs are in the stock location and I have a dana 60 narrowed to the stock A body 8 3/4 width and cal-trac mono leafs springs set up 1 inch lower than stock. Tires fit perfect with no rubbing any where. Tried a set of 275/60/15 on same wheels but the tires rubbed on turns and bumps, were only good for strait lines like the drag strip.
