New door(s)
 

Can a door with power windows and locks be converted to manual windows and locks? vice versa?

I dont see why you couldnt convert to manual. Get a different inside door cover. Some of the trucks with manual windows and locks dont have the pre-wiring for the electric stuff.

well this door matches mine perfectly already even has the white stripe going down the side, and its from a 98 even black painted, im just gonna buff it out real good and then slap it on
