Hi hope fully someone can help?
The spring retainer on my window regulator has lost/broken lug and this causes issue with winding window down.
Is there a repair ie aluminium spring retainer that can be fitted or does anyone have spare manual regulator?
Car is a ‘77 911SC but sure regulators are same and this is for NS or passenger door RHD or drivers LHD……WHY and any advice gratefully received

This is a pretty common failure as the aluminium is weak.There's someone in the UK who turns up a replacement steel part, I can't remember who / where but it may be worth asking around. I think you can get a replacement part from the US also.

This is what you need and UK based.
