I am needing internal parts to physically turn power windows to manual windows ( roll ups ) I found parts on gmpartsdirect.com but unsure exactly what parts are needed, I know i am going cut rivets off and re weld the door back together, that's not the problem, I got this car from an auction and it runs great but all power windows are shot, i had electrician go over car and all door electronics are shot, he claims it would just be cheaper and less of a headache to convert them to manual... so anyone know exactly what parts are needed to accomplish this?
