Positive Toe Angle On Diff Housing

Toe on the back of an A-body live-axle would not be good. Well there is one thing it would be good for: shredding tires. And 325/50s ain't cheap
I suppose a minor misalignment wouldn't kill the tires, but it would probably contribute to wander, as the tires tried to steer whenever they encounter a rut or an uneven road surface. And the constant squirm would shorten tire-life for sure.Modern radials would probably convert the squirm to heat tho, instead of tire wear.
