Bill, as you can see and have seen yourself with your stangs, every car is different. Even your statement above would not apply to me (springs, front or rear, did not fall out). None of this is cut and dried - we all just offer our experiences of what's worked in case it applies to someone else.
Differing experience levels play big as well (and this is not directed at anyone, but simply a point I wanted to make about myself). I do things today that would have taken 10-20 times as long if I'd done them as a kid. The first time I ever did the "MFE" method was a LONG time ago on a double wishbone car. All I had was a 10 dollar jack. I struggled like crazy with it. By the time I got around to putting delrin bushings in said car's CA's, it was like nothin. Some stuff just fights us.
