I agree, I've seen cracked flex plates make this sort of noise on other
cars.  You have to rule everything else out though since you'll have to pull
the transmission to confirm.

Torque converter or flex plate will vibrate when the van is stationary.  Rev
the motor in the driveway and check.
Brakes- did you replace the drums or just the shoes?
Did you rotate tires from front to rear?  Did you notice any difference at
all?  If you have access, I think the easiest thing to try next is different
wheels.

To continue this thread, I have replaced everything that is obvious,
bearings, cv's,tire rotation/balance, brakes, motor mounts.  As previously
stated the vibration/harmonic evens out a bit @60mph, but at that speed the
increased general noise may cover it.  At slower speeds, a hard right turn
makes it go away.  I am wondering if a weak transmission mount (I believe it
is original) would cause something like this.  The next thought that I don't
want to consider at the moment is the torque converter or the flex plate?
Again any advice about where next to look would be great!  Thanks in
advance...
