Things are going alright for me. Can't complain too much. My Cobra is at about where yours is in those build pics you posted. Its basically a shell, putting in some through the floor subs and a 6 pt. right now. Rewiring the car from scratch, nose to tail. Going carbureted. Freshening up the interior, chassis, etc. as I go. Did you use an aftermarket wiring kit or whip it up yourself?
Super Duty Complete Wiring Kit
Notice that we mounted the fuse panel where the passenger air bag went. Also, removing the heater core and all the other "under dash" goodies, we had plenty of room to wire behind the dash and even hide the MSD box.
