***05/17/21 UPDATE I purchased a second spring, knowing I would need to tap new threads to run a bolt into the bottom. But when I received it, I could see they improved the mount. It wasn't the same very thin metal of the previous one, but still maintains a small pass through hole for wires. I bolted it down pretty tight and it didn't break. I removed it, examined it, and bolted it down again, tight. So here is hoping the fixed the flaw on an otherwise great product. So I ran into the same issue as many others have with this product. As I was trying to tighten the nut, the hollow bolt on the bottom sheared off, before it started to compress the lock nut. Looking in the bottom of it, it appeared to be a thin piece of hollow metal forming the bolt that was part of a larger much more durable plate that the spring was attached to. I chose to saw the rest of the hollow bolt off, tapped some new threads into the base and threaded a new bolt into it. The base was approximately a half an inch thick and provided more than enough metal for some good threads. This worked really well and has held up strong. I'm not sure why they chose to make that bolt hollow, but it is a serious flaw. A little work on my part made this a 5 star item, but is sadly produced as a one star.
