just use the standard diff as you'll save hp and weight. Get a 4 pin LSD from a Falcon and use 28 spline MOSER axles. Or make it
"unbreakable" and use 31 spline axles and fullspool. I'm looking into making a diff housing brace for the Borg Warner just incase the 302 ever makes the hp I want. Or mini tub the corty and fit the 9". Its not hard, I did mine start to finish in one day.
A few pics before, during and after mini tubbing
2nd and 3rd should be around the other way
