The Cylindrical object on the firewall is an air/oil separator which is sort of optional (saves some oil). The square object is the heater box for cabin heat. to the right (left actually) of the voltage regulator is the ammeter shunt w/ the 2 in-line fuse holders. Thanks for your interest and good luck with your project.
I cut off the canopy at the rear bar + 25mm, made a plywood bulkhead and attached it to existing hoop fir the baggage area and extended it up to meet the canopy. The turtledeck is just .020 sheet screwed to the bulkhead in front and riveted to the fuselage in back with clips. The gear is the gun-drilled Grove Aircraft gear, 7 kg (!) lighter than the Zenith gear and much easier to land on.
