There ARE differences in the hardware.. but I thought we were discussing the *location* of the bracket for the hold down...? I really don't see any differences from comparing the AIM pages, except for the convertible versus coupe difference. I think any other 'spare position' differences, whether it be regular tire or spacesaver, comes from the size differences in the tires (in case of the spacesaver) and from differing hardware, or hardware positions...
