It is easy enough to do the Bendix upgrades, and the improved full pressure, inert bearing engine swap on an AD chassis.
The Task Force truck drive train is not a vast improvement over a '54 AD, not to mention the front wheels will hit the front fenders. ( I guess I just did mention it, but nevertheless...)
