Hi, I have a 2003 RWD Infiniti G35 Sedan with 122k miles, and I'm planning to replace the front lower control arms on both sides (forward and rearward...or lower control arm and compression rod...whichever you prefer to call them). At any rate, my question is primarily about the front lower rearward control arms (compression rods).

1) In my search, I see that there are the following Moog part #'s: RK621340 vs RK621373. Different sites seem to say different things. I have seen some sites say that one part # is for 2003 only and the other is for 2004-2007. I have seen one say that it is for RWD only. I have seen one say that it is for coupes only. So I have decided to ask you all what you know to be true...which part do I need?

2) Is Moog a respectable brand? I don't need top of the line. I'm looking for a reliable brand that still keeps me under $100 each for the rearward control arms.
