i use mega billets and they all had the threaded pin, have a forged mega and you have to drive the pin in. i use a tooth cut to less tha 1/2 inch and use it as a guide, get everything in place with the toothpick and then let the roll pin ,,,well roll,,,it drives out the toothpick and you're good to go. i use the blue 2" painter tape wrapped around the area to prevent those unsightly dings <laughs>
