Yet another video update. Here you’ll get a tour around the car pointing out the newest additions, followed by fabricating the fuel swirl pot and mount, the first power-up of the electrical system, mounting components on the instrument panel, drilling the firewall for fuel lines, fabricating braided stainless steel fuel lines, building and installing the throttle pedal cable pull rod and the cable itself, building the ECU mounting platform, and machining the rear sprocket to fit the differential.
