Okay, I made the mistake of looking at "Cam Bolt Kit" and assuming it was a pair. It is not. This is for a screw. It was really easy to install. You can find videos on YouTube showing how easy it is before you buy it. It was $16 less than what my local NAPA wanted to charge me and $24 less than the other parts store wanted. It's worth waiting a few days if you don't need it ASAP.
