possible to add power windows and door locks?
 

i am looking to buy a 99-2001 SD SC or CC. i am looking at some of the XL models and they dont have power windows or door locks. is it possible to add these options to these trucks? maybe by just changing the door panels to the powered ones and running the wires? the truck i have now, i just put power windows and door locks in it and i dont think i will ever go back to manual. thanks.

JC Whitney sells power window kits for Super Duties, they're about $230 and you can easily install power door locks that work with an alarm and remote. buying an XLT is probably easier.
