You could run the Unilight directly to the coil (bypass the MSD) and start from there.

If it's a Unilight, is this a points distributor thats converted? If it is put points and condenser back in, feed this back into your MSD to verify it's not fried as well.

Get a voltmeter on the power leads to verify power and trace the wires back to make sure you didn't miss any inline fuses.
