I ordered a new left rear knuckle a couple weeks ago from San Leandro Honda after getting an inspection done at my local Honda. Problem was that they both gave me different parts numbers. I went with the SL Honda number because I spoke to the parts dept on the phone and they explained why the other number was wrong. Problem is, my mechanic just told me the knuckle is the wrong part and won't bolt up.

So for anyone who is more familiar with the parts catalog numbers could you help me figure out which parts number a left rear knuckle for a 2002 S is?

Local Honda: 51215-S2A-010 (SL lists this part as a front knuckle)
SL Honda: 52215-S2A-000 (SL lists this as the left rear knucle, but it is apparently the wrong part)

I appreciate any help because I really want my car back from the shop and these delays are killing me.
