there are quite a few, can you explain to us in more detail what she means by "it's a hair short" ?? like the cord itself doesn't reach to where she needs it? or the cord doesnt fit the plug?
and they do make normal usb ports that fit that plug in your car
take a look at your local Best Buy, i've done a search for you already on their web site and im sure you'll find what you need here

hope this helps
