74 Duster, resto mod 6.4 conversion in Australia

The idea being that the lower portion becomes the collapsible section in the event of an accident.....and it makes it super easy to install and remove the lower section without disturbing the upper.
Am i correct in saying that once column is installed the lower shaft can be removed from column? As thats half the issue with the holley system that everytime you want to remove motor you need to remove column
Also i cant find this part for sale anywhere cant see it on the hdk site either. Do you have more pics with it installed etc?
