This was my first carbon spinner. The back-plates are not predrilled so you need to do a little engineering and layout to transfer the bolt pattern. I used the combination of a drilled prop and the drill guide and bolting it to the back-plate. A little tedious but it works and looks great. Be sure to check the balance of the spinner afterwards.
