A word of advice to the NTC3 drivers, use 3mm screws on the cases, they wont strip as easy, you can also use them on the suspension arm shock mounts. The heads of the socket heads screws is litttle big, but they fit great. Button heads work great too, and the heads are not as big. When I had my NTC3, the the 4-40 screws stripped in the first 2 months. I would pick the car up and turn it upside down and a few screws would fall off.
