Well, I was wrong, both Flash 1 & 2 use T6 for the pivots. I was not familiar with Torx bits and I was going by the appearance of the little stars inside the pivots, and I was therefore trying to use the wrong sizes.
Another thing I find is that if you put a little piece of towel paper over the pivot hole and then slip the T6 screwdriver into the pivot then it fits like a glove. I saw someone on YouTube do this, he said it will help prevent stripping of the screw or the bit. Adjusting the pivots work much better with this little trick.
