Why do you need the extended shackles for the anti-sway bar, since it
came with the stock shackles, or am I missing something?

Anyway, I don't think an inch or two of shackles will make a significant
difference.  You will decrease your already minimal caster because you
will be rotating the rear of the axle up slightly which decreases the
caster.  I think you will actually decrease the front U-joint angle a bit
as the diff should tip up more than it drops down as I think the rear 1/2
of the spring that the axle will rotate around is shorter than the front
driveline (at least I picture it that way--if the driveline is shorter,
then the U-joint angle will increase)
