It's not like the OEMs are all that great. It's also not that critical a part and there is no performance issue, just longevity. I only noticed mine were broken when I'm was under there and saw it.
I replaced with Autozones and they appear just as good. One side has been on seven years, the other three. Cost was twenty something.
I see no reason to go OEM-obsessive on this particular piece. It's no LBJ.
