Converting Rear Manual Windows To Power On Extended Cab

[mkruluts]

I Have a 2005 Chevrolet Silverado Extended Cab, this is a nice truck but lack in one thing. I always open the rear windows to allow air to flow freely and not at resistance. It is an extended cab so obvisously I have to manualy open the windows. I would like to convert them to power windows. Does any body know of a GM truck/suv/van that has something i can apply to this or maybe a universal kit?

Assuming these are the latch windows that just open vent style, you should look at minivans as the big side window have power options to vent them the same as ext-cab windows, Caravans i know they all seem to have them but not sure about GMminivans
