We have a 1995 Wrangler with half doors, and slider windows on top. I am having a hard time finding the bolts that connect the windows to the doors. They are a screw like part with an insert on the bottom that acts sort of like a molly I think. Has anyone replaced these, or know where to get them? We ordered the replacement screws and they came without the insert on the bottom. Any information is appreciated. Thank you in advance.
