65 Dart 225/55 R16?

225/55 R16 w/ +24 offset (so I am assuming about 4.75" BS) on a 65 Dart with a 8 1/4 Rear? I know the rear is just under 2" narrower then the 7 1/4 that's on there now, and I am currently running Ralleye wheels with 235/60 R14, so I am not really too sure if when I swap the rears if the LBP wheels I want will fit properly. Anyone with info or input? I'm pretty sure they wont fit but want to make sure.
Thanks
