Second - Stance: It looks like your stance is too narrow. Toe angle looks acceptable but may be a bit narrow.
Third - Grip: From these videos it actually looks like the bar may be too high up. Your upper back doesn't look TIGHT, it looks rounded from the start to finish of every rep. Your wrists are also in extension, you need to put some flexion into them and get them closer to neutral.
Fourth - Hips: Get your hips farther back and cut about 2 inches off of your depth. The top of the patella ought to be just above the hip crease.
I do not have my blue-book on hand but all of this is covered thoroughly in the squat chapter.
If you can get into a training with a coach it would be worth your time. Sometimes no manner of self correcting is enough when you're focused on the weight on your back and you may NEED a coach to help you get into and maintain the proper position. Respectfully, you have wasted enough time in your training career if you are in your 40s/50s. Get into a session with a coach and help prevent any more of it.
Side note, I'm NOT an SSC, but have wasted plenty of time myself and I have more to waste than you (I'm 27). Getting in with a good coach is worth every moment.
