I was just out trying to fit my new regulators to my C5 but they are slightly different to the ones I pulled out of it.
The ones I took out have a guide hook beside each of the four bolts but the new ones don't. the motor fits. Does anyone have any experience with this and is there a workaround, I can't find a picture of my variant anywhere? window is currently held in with old snapped regulator. Bought of Mr Auto will accept return but charging shipping and restocking because its over 30 days
