[P.J.]

I installed a set of power windows and door locks on a friend's car a few years ago. It was not hard if you get the right tools to drill the holes in the doorjams. Use a good hole saw
from a machineshop suplier and a slow angle gun. Lubricate the hole saw and slowly cut until you are through. GM puts the dimples in the body so there is no guessing.All the wiring plugs in your fusebox front to back and the power windows fit right in the existing holes.Be real careful if you need to remove the power motor for any reason be carefull as the lifter arm is spring loaded and it will release like a guillotine and can do real damage if you don't support the spring tension before removing the power motor.
