Thanks Andy. Got delayed a bit because the disc brake was secured with Torx screws (the type that I of course didn't have) so a 2nd trip to the hardware store was required. So that's 0 for 2 when it comes to cannondale.
Here is the mounted wheel with disc break. Note: Swytch used Allen hex screws (like normal folks). Note 2...there is a gasket that covers the disc side hub. I had to remove that when I added the disc because it pushed the disk out of alignment and was rubbing on the fork. Putting the gasket on the outside solved that (see photo).
