Been stuck on trying to get this ******* thing out forever. Getting frustrated. I've read that you have to turn it so the black part of the MC fits the in square in the firewall then simply pull it out. Problem is I can't get the thing to turn at all. Grabbed into it with my life with plumber pliers and I just keep slipping off and digging into the thing. Don't want to damage it. Is there any tricks I'm missing here? Have already disconnected clutch pedal btw
