Spare tire question for 69 Dart

I used to carry a 17" spare from a '07/08 Infiniti G35. Fits in the well, clears my DoctorDiff 13" cobra style brake kit in the front too. I think it has a 145/80/17 on it (~26" tall), not sure if you have a sure grip or not but you'll want to match the tire height with the rear tires if you do. That's gonna be the tallest tire that will fit in the well. I did a little dremel work on the hub bore, it was a couple mm's too small for the DoctorDiff hubs. Nothing major though, especially for a spare.

It doesn't sit perfectly even with the trunk floor, the center of the rim sticks up just a little because of the curvature on the spokes. They do have a steel rim spare for the G35's as well that's a smaller rim diameter. I needed the 17" aluminum version because of my 13" rotors.
