C body Inner tie rod end dilemma

I'm putting my front suspension back together with C body tie rods. I bought everything from Rock Auto and one of the inner tie rod ends is different. I called Federal Mogul (they own Moog now) and they said it's a new design to give the stud more travel. I'm a little concerned that since the stud necks down that it will be weaker than the other three. Here are some photos. The first photo is what three of the tie rod ends look like. The second photo is the new design that I'm concerned about. Oh yeah, the part # is the same on both.

Thoughts?
