I've always just used a big pry bar to move lower control arms. But now in my sixties and a one-man operation, I was considering shelling out $200+ for a fancy lower control arm tool when I came across the OTC #6007 for under $20. I thought, "what do I have to lose"? So I picked one up. It works really good. I use it with the OTC #7168 30" round pry bar (and sometimes a pipe on the end of that). It will fit and pry bar that has a max diameter of 7/8", preferably round. Highly recommended.
(iATN Note: At the time of review, this product was titled "6007 Lower Control Arm Tool by OTC").
