B body rear in an A body

The two cars have 14x6 rallyes, IIRC and they are darn close to the outer well.

To get the tire in the stock location with a 7" wheel, you need about 5.5" of backspace. A pretty shallow face on the wheel.

I had a picture of the tire in the well, lost it. Maybe I can go take another.
Here is one of the cars.
