What are the best option for French sliding door blinds

I called Bali, the manufacturer. They were able to look up my order based on the number on a sticker on the blinds. They said the entire headrail needs to be disassembled to replace the cord. They cannot send me a cord and instructions. There is a lifetime warranty, but since the previous owner purchased it and my name was not on the warranty, the warranty is invalid. It looks like I am purchasing a new blind. They said you could buy just the headrail, but my wife would like a different color if we are going to have to take it down anyway.

If anyone has one of these blinds and you know who purchased it. Make sure you use their name when you call or email them.

I have 2" blinds from Lowes, probably the same one. Our windows had enough over hang though. If I recall, there are little metal rectangle boxes that get mounted / screwed into the top of the window, and then the the blinds slide into the little metal box to hold it in place. These little metal brackets have numerous holes in them on both the side, and on the top. I think there were four screw holes, one in each corner on the top, and two on the side. If this is indeed the type of bracket your blinds come with, then you would most likely be able to get three screws in place (1 side and 2 in the top). Then repeat that with the other side of the blind.

This should be more than sufficient to hold it in place. I think it would look a little funny though, I would probably go with a 1.5" for looks. But you could use a valance to cover it up and no one would even know.
