Finished riveting bottom, forward skin. Enclosed firewall wire pass through with firesleeve. (Note: the location of this pre-dilled wire pass through is right behind the engine mount and it makes it very difficult to encase the wire bundle with firesleeve. Suggest covering the pre-drilled pass through hole and relocating it about 2 inches down and to the center of the firewall for better access). Installed the crankcase breather line to the engine fitting.
