Torx size question

I bought new tailgate cables for my 2001 Dodge Dakota and I see the cable is attached by what appears to be a Torx bolt to the tailgate. I don't want to go out and buy an entire set of Torx bits, so can anyone tell me what size Torx bit I need? That is....if it is a Torx bolt to begin with.

Thanks!

A Torx socket set is pretty cheap and quite handy. Buy the set, it will be useful in the future.

Thanks MagicRat. I did consider that until I saw that the cheapest entire set at the auto parts store was $15.00.
I know $15.00 doesn't sound like much, but if you are retired and living basically on Soc. Sec. and wondering how you are going to pay the next power bill, $15.00 seems like a lot of money and tends to make one tighter than the bark on a tree.
I do have several Torx bits that I have bought one at a time when needed over the years but, wouldn't you know it, the size I need is the one I don't have, and the ones I do have I probably used once in my life time. I'm hoping to hear from someone who knows for sure what size I need so I can borrow one from a friend or pick up one for a couple bucks at some discount tool store next time I'm near one.
Thanks again!
