99 gmc seirra

[ChevyMonkey]

hey all, i just got a 99 gmc seirra step side ( no pics at the moment), i was wondering if any nows a site somewhere that shows how to install power windows for this year truck, im gonna atempt my own way of doin it but i thought i would check and make sure theres not a differetn way of doin it first, also what r some of the ways u can check to see what kind of gears u have, like clues or something, like i got towing hooks on the front of the truck which would make me think it would have 3.07 gears in it, is there something else i could look at without taking the cover off.

thanks
