This was my dilemma a few days ago. My friend shipped me a bike that I bought off of him and I ended up stripping the stem screws for the face plate. It was a front loading quill stem. I ordered a new stem, but unfortunately I don't have the tools to replace the old. So I thought about it awhile and came up with a way to take the bike down to my friend's house. He works at the Lbs and has alot of tools not to mention skillz.
This is what I came up with to take the bike to get repairs. I rode this set up about 12 mi .round trip.
