@cvdup https://www.cycletouring.co.za/ carries touring bikes and the full kit. Grant is a tourist himself, so full of good advice, and if he doesn't have what you are looking for, will be able to help you source it.
@Jackeswe have all of that and did it. I can't give you specifics of why, as my wife is the brains in our house, and she, trying to work through all the changes, believes it will still benefit us. I seem to recall it was for the life insurance, but I stand to be corrected.
I've been down this road. Importing a set of rails was just too much of a schlepp.
Keep an eye open on the classifieds and perhaps put out a wanted add yourself. They don't work for everyone so lots of people have one sitting in a cupboard somewhere.
We have 2 cars insured with Momentum. Both cars are in my wife's name. Only she can get SafeDayz now, despite me also being a registered driver on the insurance. Seems crazy to me......
Not sure which Silverback frame you have, but the majority of frames will comfortably fit a 2.25 only. When there is mud around even that becomes too big.
