Drivers window is slipping down at the front when i put it down. I have to also give it a helping hand to go up

I have had a look inside the door without removing the regulator and one of the arms has snapped.

I was wondering if the regulator for a type r classic is the same as any other impreza sti saloon etc? I know the window is longer on my type r but not sure if the regulator is the same

Dont want to remove it until i have a replacement.

On the picture the red line is where it has snapped and the green circle is where it is still held on the rail by the wheel.
