I have a 1994 Chevrolet CK-1500 Truck and I need to replace the driver's side mirror. How do I remove the old side mirror? I believe I need to remove the inside paneling off the driver's door to get to the nuts holding on the mirror from the inside, but does this require a special tool or how do you do this? This seems like something I can do and I already purchased the replacement driver's side mirror. Can you walk me through this process?
