i dont see this popping up with OEM cables at all, so i'm not sure we solved anything 'over the years' when the problem doesn't happen frequently to begin with. So likely, when you're installing these cables, something's going wrong. Either poor routing, wrong orientation or incorrect tension. Check the FSM if you aren't sure on any of that.
Hell it could be alot of things, but to get any help from us you're going to need to do more troubleshooting. With your questions as of late, it's too vague to draw a reasonable conclusion because you're simply saying it happens and leaving it at that. You aren't rolling any ideas around, you aren't performing any troubleshooting before asking, you're just assuming we know exactly what's going on. I know personally, I've been more than patient (especially when you say you're missing a ton of bolts by a motor mount but don't replace them and keep asking). So here's my suggestion right now. Get some more details, double-check everything, and pictures (especially here) are a huge plus. I read your post above and honestly you're going to need to do some more troubleshooting and be meticulous no matter what you do. Note anything that seems odd, give details on the cable and clutch you're using, and if it snaps again pay close attention to what happened, when it happened, and anything related. Snap some photos of what you see so we can see it too.
If you aren't good at this troubleshooting thing, ask someone who is. Troubleshooting is a big reason why mechanics get paid what they do at many shops. Anyone can turn a wrench, but it takes time and training to know what's going on to be able to fix it properly. Bear in mind you're doing this over a forum vs in person, so that makes conveying the issue 100x harder, so anything you can do to make it easier will get a better answer faster.
This may seem rude, but honestly I want to help but I'm sick of playing 20 questions with you. And honestly, you're the only one I have this issue with.
