After the low-tech, lame bungee cord fix (that lasted about 2yrs while SLOWING window movement upward), I did this and haven't had any problems for 3yrs ....

(I did the simpler method shown in pic #3 of post 1.) BTW...I did have the saggy regulator guides too. The roller screwed to the arm prevents sagging. I also tried the washer/adjustment approach with marginal results.
One of my brackets was cracked so I reinforced them with metal (custom-fabbed at home). That's also held for 5yrs. Those SBC brackets look like a great design. Brackets aren't what holds the regulator on the correct path though.
For more fun, this thread has LOTS of posts on the window subject
