Mike,Since I am waiting for the first intermission between the Devils and Canes to end here is another option:
16" space saver wheel from a 2000ish F-body with a Prius 205/60R16 mounted on it. 25.7" diameter.
I do like the idea of using the late model F-body 16" space saver. I think that would work like a charm.....and with the Prius 205/60 x 16 tire. I think that would provide me what I'm looking for. Thanks for the suggestion.
