No I do not want something that goes outside the door. That is why I want to get something that slides into the bottom of the door. do you have anything that slides into the door as opposed to something that slides onto the door?
I'm afraid not. Many door manufacturers design sweeps this way, but each door manufacturer makes them to a very specific size, and then discontinues them when a new line of doors is released. This makes it incredibly hard to find sweeps like yours, that are made to a precise size. I personally find the wrap-around sweep to be an easy solution to an otherwise complex problem. If you do not want to use this hardware, you would need to contact the original door supplier to see if they have old stock laying around you could purchase.
