The one I borrowed from advance Auto worked the best for me Compressor. I tried a couple too and made my own. The one I made worked great taking it out but not to good going in. I had to compress it a little to get it in the control arm.

The link I posted above, you have to make sure the bottom claw, one side of the arms needs to be able to be unbolted. Insert the claw from the bottom hole. Then screw onto the long screw rod inserted down through the shock hole.

Then insert the arm piece you unbolted from the claw and bolt it back on and adjust into the spring.

You can not insert the whole bottom claw up through the bottom control arm because there is not enough room. It has to be taken apart and then inserted and re assembled inside.

I worked on this for a week reassembling the coil springs. Tried different tools and this worked the best.
