Would something like this work? I don't mind mounting on the roof rack, as I assume this is what this is for.

I just bought a Pathy LE from 1995, which has the apre tire mounted inside the trunk on the drivers side. I'd like to be able to use that space. Where could I find a spare tire carrier for the outside of my vehicle?
