It does have internal “stops”, they are in the motor itself.
They are made of plastic, and deteriorate with age, usually crumbling into what resembles a GAA grease. They are cheap and easy to replace with the new nylon parts.
Some people would use a 10mm nut, but that doesn’t have any give to it.
Usually when they fail, the window won’t go up/down and people assume the motor is bad.
Check that. There is no reason your regulator shouldn’t last another 20 years or more.
By the way, GTS cars could have any and all options added back and factory installed.
If you didn’t want something that was standard on the GT package, you had to go GTS to remove everything and then add back what you did want.
It’s misleading to think of it the same way as the foxbody stripper cars.
