Cragars rub!!! Help

I bought 4 sbp Cragars from a member here...took the car to the tire shop, the rears fit fine but the fronts rub bad on bottom frt of frt fenders...so bad, we took off the tires and the guy loaned me a set of new tires and put them back on the stock wheels to get the car home... The wheels on frt are 14x6 with 215 R 70 BF Goodrich tires.....14x7 with same tires on the back......Tire guy says tires are too wide and too tall.....said i should try 215 R 60....Opinions??? i dont know what the backspacing on the Cragars are.....here's a couple of pics... its a 65 dodge dart gt vert
thanks, John
