Started to add the Rivnuts to the firewall and add items. I added the coolant overflow tank, battery box, Brake reservoir, and the rubber support mount for various other items Much more difficult was the fitting of the cowl strip. This required aligning 4 pieces of metal that run from the top center along each side of the fuselage (right & left). Starting from the outside you have.... fuselage skin (dimpled)...a spacer strip (need to dimple) .... then the firewall (came dimpled).... then, finally, a thick metal strip (need to dimple) this holds the Dzus fittings. Most of it aligned however, at the bottom ends the factory got a little wonky with the pre-drilled holes. I decided to use one of the pre-drilled holes and then offset and drilled rivets equally to make the last part of cowl strips secure. I am starting to get used to fixing these type of problems (always consulting AC 43, of course!)
