What Wheel/Backspace/Tire size for you who are running a Ford 8.8" rear end?

I'm doing one of my Darts low-buck and Slant 6

I've read up on the 8.8" swap and talked to the local rear-end shop about trimming/etc.

Need to get some rolling stock for when it's under the car.

Anybody running an 8.8" rear end got max sizes/backspace recommendations for stock wheelwells for an early A body? (64 Dart)

I'd like to stay with 14" or 15" wheels.

Thanks!
