I'll be honest - I never tried. It lived and died, in the trunk of the Town Car.
Supposedly there's a similar spare in the trunk of my current Mark, but I presume it's more mustang-y. I've been told it will clear the caliper on one end, but not the other. (It fits the rear, I presume.) which is a "good enough" fix for me. If i'm in that kind of need, I can swap two tires, and limp it home.
I should take some photographs, for the good of the people.
