broken vent window

[staggerd86c-10]

hey guys, i hope everyone had a good weekend, over the weekend i managed to finish installing the motor in my truck which is 2 steps in the right direction but yesterday i started cleaning the truck and i managed to break the passenger side vent window by pulling it in too much, ihad that stupid paper wedged up in there and tried to make it tighter. my question is how hard is it to change out the whole vent window assembly im planning on going to a junk yard to find one. if its not too hard you think you can give me some pointers on changing them out?
