Kyle,as I've also mentioned to MVK be careful when you remove the handle from the vehicle.After you remove the screws it needs to be GENTLY wiggled out,dont just tug and pray!The part which connects the barrel to your door lock is a flat bar approx 2-3 inches long.This has a tendency to snap if not treated with some respect.
I found all this out when I needed to change my own drivers lock,damn door could be opened with a screwdriver when I got it.Well I snapped the bar on the donor car's driver's side handle.So I figured what the hell they look the same,in for a penny in for a pound what had I got to lose.Thank god it fitted that saved me some serious dosh.To make sure you know how to do it I would recommend getting one from a breakers,at least you can have a dry run with the other door.
Catch you later.Bear
