Setting Fence Posts

Hello All...
I am going to be setting some 2 3/8" x 8' corner chain link fence posts. I would like advice on:
1) How deep should I dig the hole, and put concrete in, to insure the posts do not raise up during winter/ground-freezing? I think the frost line here in Michigan is 24".
2) What diameter should the hole be?
3) To what depth of the hole should be filled with concrete? That is should it not be above the frost line? In other words if I dig a 3 foot hole and the frost line is 24" should I only put concrete in the first 1 foot of the hole?
Any information appreciated!!

I can't speak for concrete depths, that's one job I have always managed to stay away from! But I would double check that frost line. Here in NH, the frost line is 42", some places are 48". Your town building inspector will know, and they are very happy to give out such information. He may also know about the depths for concrete fence posts. Never hurts to ask what the locals want.
