1969 Race Dart w/ 426 Hemi- garaged for 45+ years

A real "BARN FIND". Being an original 340 swinger, I wonder where the D.A.R.T. emblems came from on the front fenders. They would not of came on a 340 Swinger. I like the original HURST shifter put back on and all the meat on the rear rims. Is that 15's on the rear and 14's on the front?.
