I have a 73. If your car has a factory style rear suspension, I believe it is not uncommon for the rear end to be slightly offset. Most of the time this is towards the passenger side. I run 18x10 in the rear with 5.5" BS on driver side and 5.75" on the passenger side with a 285/40/18 tire. This was necessary to get the tire inside fender without rolling the lips. I did have to flatten the seat belt hump to get a comfortable clearance on the inside.

Go with a 275/40R18. It'll look better proportionally since it's closer to the stock height 225/70R15s.
