Duster rear end compatibility

Just so you know;
as for the 7.25, if that is what is currently in the Duster,
will not BLOW up with the first throttle application;
Not even with a hi-torque 340........
so long as you don't shock it with neutral-drops, nor peg-leg it, fresh oil could carry it for many years..
A limited slip will be a life-saver. However,
I would NOT run it behind a 360LA with a clutch, unless it was a dead-stock Lo-compression unit.
