Jan 2005 You can use the mini spare from a ford Escape. It is 26 to 27 inches tall. I tried the spare from my Escape and it fit my avanti front and rear and fit in the sppare tire well. Geno 64 R2 Avanti Cherokees from 84 to 2003 should all be about 26 inches, a lot narrower that standard tire and fit in the trunk well easily.
