Hey guys I have a 98 chevy k1500 as you know the upper door hinge holds the roller pin which the spring arm rides on to keep your door open. Well due to stupidity on my part of putting weight on the door everytime i get in the roller is now at roughly a 45* angle to what it should be. I have found replacement roller pin and need to replace the door side half of the hinge but i am not sure on how to remove this. Does the hinge have studs that run inside the door and secured in that way. Any help would be greatly appreciated
