Half of you guys would have crapped your pants if you watched me pull front springs out of cars and put them back in with two crow bars in the years that I was doing it all too often. I've never used a spring compressor on a regular rear wheel drive car with A frames like a Chevy Impala. I've used them on those Fords with the spring on top of the upper A frame as there no other way to do it. I won't say that I haven't run a chain through a lot of them to keep them from taking off when they do pop out when I am taking them out though. I'd bet that the guy on the left moved right after the photo was taken back to where he normally stood and where the camera man couldn't see his face right after the photo was taken. Blowing the photo up so you can see the details shows that it wasn't going to slip off the lower A arm and the other end of the clamp most likely hooked into the shock tower and wasn't going anywhere. that means a lot.
