How hard would it be to go to a junkyard and take the inside of the door off of another truck (driver and passenger only since I only have a supercab) and put those on my truck installing the power windows as well as locks and possibly power mirrors. I really wish I had power locks, windows, and mirrors, and this seems like it would be the best way to do it, but would this be really hard to do?

 

Taking the door apart, would not be bad at all.

The trim panel ( if you can find the correct color ) is a real easy pull.

You can get an idea by downloading the directions from Muth signal mirrors.

The wiring harness, you are only going to get so much ( to the door hing area, then inside maybe ).
The one that is going to take some time is trying to take out the power door lock actuators, and the power window motors ( those need the dimples drilled out to unbolt the motor easy)
You might be better off getting the door panel, and factory switches ( and connectors on the back of the switch ) from the bone yard and then purchasing after market ones.

Give Travis at KC AutoSound a call, and ask him, he can tell you the straight story.
