245 60 14 on 69 Dart

I also have a 1969 swinger and went with 14x7 on rears with 245-60-14..... After i tried 14x8 wheels with 245-60-14.... The 14x8 wheels fit with out rolling lip ... BUT right side outer tire SLIGHTLY rubbed lip... I am sure if i finessed diff slightly towards driver side i could of corrected this... THe only reason i decided to go back to 14x7 wheels .. is because that 14x8 rim and a dog dish just does not look right ...

Steverdart is that a 4 speed or auto ?
