Trimmed the sides of the top cowl to fit the joggle on the bottom cowl with a dremel and a body file. I then drilled and clecoed whilst pulling the cowl tight to the fuse. Fitted the camlocks as per Jabiru instructions.
The spinner backplate was predrilled with pilot holes for prop bushings to suit the timber prop. The carbon prop uses the second set of holes on the prop flange which are smaller and closer to the center point so I had to remark and redrill the backplate to suit. Temporarily fitted the prop so that I could make a template for the cutouts in the spinner cone.
trimming was done a little bit at a time to achieve a good result
some of the camlocks will have to be replaced with shorter ones as the cowl thickness varies
might remove some spark plugs so that I can check the trueness of the prop and backplate
