So, I may be picking up this 84 Cutlass 4-door, and, like I've noticed in many 4-door malibu's, the windows in the rear doors do not roll down, due to no cranks equipped in the car. Honestly, I'm not crazy about this, so I was wondering if its possible to convert the rear doors to have working windows. From what I understand, the car has no a/c, so I need all the airflow I can get! Help me out, please!!!
