Hi Bottlefed, love your build pics, i am also building a Countach but its been two many years in the making.
The only concern i have is the mounting of the fuel tank in the front of the car, have you run out of room in the rear, the only reason i mention this is i believe Lamborghini had real proplems with the old Muira, it also had the tank over the front wheels, and as the tank emptied the steering got very light to the point that the car would understeer badly, if it was me i would find room in the rear, perhaps two tanks like the original, i noticed it's a fuel cell, but being oldschool i still don't feel right having a tank up front in a crash, other than that your car looks great, gives me some motivation to go out in the shed in the middle of winter.
