the spinner back plate goes on first, Install the spacer ring and then the back plate , the prop, I agree with the selection of props made in the previous post , if it does not fit , then some reeming maybe required , install the thrust washer and nut , it is helpful to check the clearence of the spinner before completely tightening the prop nut ,the prop should not touch the spinner anywhere , if clearance is good finish tightening the prop nut and install the spinner ,tighten it down pretty good ,

happy flying
