Supercuda's on the way back...after18 years!

Looking for some suggestions Guys and Gals..

I need a spare tire for ole Supercuda. I am considering a space saver spare (donut ) from a Ford Escape as it is the correct bolt pattern and is 24" in diameter with a 16" wheel. I want the spare to be able to be stored in the trunk well and still have the trunk board flush with the trunk floor.

Wilwood 11" front disk brakes /Mopar 11" x 2.5" LBP drums in rear.

Any suggestions would be welcome.

Thanks!!
