Pros and cons of using a B-body rear axle assembly???

How wide a wheel do you want to run?

I had a bone stock 67 Coronet axle in my 73 Duster.
(no mods, just dropped in with a little nudge)

Looked better with the same track front and rear, and was running 15x6.5 rallye wheels with 225 or 235 width tires.
