Interesting? I've found that if you throw them into a container when it's time to put them back their lengths automatically sort themselves out. It's easy to see which ones are too long once the threads are engaged and which ones are too short to engage. Also simply looking at the part often helps determine where the short and longs one go.That’s one thing I do very diligently is set my bolts out exactly as they came out as I learned that lesson years ago the hard way lol
