Well I was into this gen truck way back in high school, and there are several answers to the PW situation, Summit I believe sells a kit that just puts a deal on the crank stub and turns the shaft that way, or you can do the whole kit that has the lifts and all. As far as keeping it retro style, the trickest thing I've seen so far, was to reuse the factory handle as a switch for the windows, it didn't spin only moved a little but up was up and down was down, pretty sweet.
