I've read both of those and the first one says 14mm and the 2nd one says 17mm, that's where I got confused.

I'd just buy a set that has both, shouldn't cost you too much more.

How frustrating. After driving all over god's green earth of Kansas City, Sears only has a 17mm. So I buy that I find out it's too big. But they don't have a 14mm so now it's time to find that. I'm pissed already and I haven't even started the CV boot replacement.
