i think the paint colors might be slightly different. i dunno for sure. the rim width and backspacing are probably similar. the centercaps and trim rings will be different, but can be swapped. a judge could probably tell the difference at a glance.

they are probably not exactly the same as the 68's, in that the 68 14" rims were made to clear the big ol' calipers, and these probably will not.

most of this is just a semi-educated guess though.
