These old trucks are narrow, but I don't know if an AD will fit in a tow dolly? Probably not a great idea even if it does fit.

If you tow it with the rear wheels on the ground pull the axle shafts or driveshaft so as to not damage the transmission.

A flat trailer really would be the best way to haul it.

200 miles is not that long of a drive, if the brakes work good and it runs decent you should be fine. I've driven thousands of miles at 50-55 mph it's fun, 200 at 40-45 should be easy..

Another option is a tow bar, but should probably be your last option. Here is a picture of one suitable for a medium sized truck: http://rides.webshots.com/photo/2664430520080251109waGtyD
