Yeah, I believe 6.25x is denoted as 6.2x in their database, for some reason. You can send them an e-mail with any questions--they generally reply pretty quickly (there's an e-mail address listed in the Contact Us section). Would also be a good idea to ask if the spacebar color(s) you're interested are in stock. Their inventory lists get updated once a month or something like that, so it's possible that some caps you see on the lists are no longer available.
