The selector detent pin spring won't fit in the channel/hole for the take down or pivot pin detent springs.
On an Aero lower I just took out of the box, the pivot pin detent spring hole pinned at .095; the safety selector spring hole pinned at .126.
According to my chart, the safety selector spring is .10 in diameter, the safety detent pin is .124; the pivot pin spring is .088, the detent pin is .091
I've always used the selector and ejector springs interchangeably - they are the same length and diameter.
ETA: when I was tapping the rear take down detent spring channel, I shortened the spring only the length of the set screw. I used a razor blade to hold it level and used a good hex key (not ball end) to hold the set screw solid against the razor blade as I slowly lid it away. Another option is to use a longer set screw and shorten the spring more, but I didn't like that idea.

Patriotism means to stand by the country. It does not mean to stand by the President... - Theodore Roosevelt, Lincoln and Free Speech, Metropolitan Magazine, Volume 47, Number 6, May 1918.
Every Communist must grasp the truth. Political power grows out of the barrel of a gun. Our principle is that the Party commands the gun, and the gun must never be allowed to command the Party Mao Zedong, 6 November, 1938 - speech to the Communist Patry of China's sixth Central Committee
