Manual vs Power Steering Shafts

Can i ask why you dont want to use an adapter? As about to purchase a manual box for my one and going to use an adapter that comes with the box. Is there an issue with the adapters?
There’s no issue with them that I’m aware of? I’m doing the same thing this spring. Luckily I was able to buy a used PST box and a new adapter for $50.
