I only needed one of the 90 degree pliers and for double I got four. What I really needed was a snap ring removal tool for the sneaky large snap ring on the front cam seal of a 2000 Saab 9-5. Last time I did this job I removed it with a small pair of snap ring pliers to which I attached aluminum tube extensions to the handles (I happened to have them on hand...) It barely worked and I needed another pair Hands. WEAR EYE PROTECTION! These clips fly! So I ground about 1/4 inch of the 90 degree plier tips to fit the small holes in the clamp and after that I had to squeeze the clamp to get the sharpening points into the holes. And yes, I had another pair of hands, but I probably could have done without them.
