In an attempt to take off my door tops this weekend I broke a stud. It was incredibly rusty so I imagine the remaining one is as well. My glass is still good so I would like to buy the $90 tops sold here. My question is do they come ready to install glass or would I need to also buy fittings? If they don't come ready to go: would I be better off getting the $200 tops? I guess I should also ask if there is another source I should look at. Thanks
