Is there a way to fix a busted port on the mb without the piece?

Brandon d it would be an unwise choice to do so. If you are going through with it you would have to solder fine leads to each copper tab on your flex cable and solder those to the board without shortening it and without turning it. I suggest you purchase a replacement/donor board and desolder the connector on that one. Use that connector for a replacement on your board. If you want to solder something then that would be the way to go. Post some pictures of this connector with your question so we can at least try to find the right one for you.
