Here's what the strut coil spring compressor looks like. Ignore the fact that I'm using two different ones(from two different sets). One of mine got jambed/stuck somehow during use and I couldn't tighten or loosen it so I had to cut it to get it off then used an autozone loaner to finish up. So I had one of mine and one of autozones on the spring.
The one from autozone(bottom) is significantly better and easier to use. And twice the cost lol.
