Hey John, this Les in St. Louis,Mo. I have a couple of factory sliders up in my garage attic. They have been taken apart and I was going to see how they would buff out but never got around to it. They don't really rust because they are aluminum,the aluminum will get a hazey look to it, the only part that will rust is the brackets and screws that holds them together.The factory sliders have pretty distinct features: they are not welded in the lower corners they screwed together. The latch was still available a few years ago from GM because they used that latch for many years. I can take some pictures if your interested in seeing them.
