Do the right and left upstream oxygen sensors on the 1999 3.0 XLT have the same part number? I noticed e-bay has some listed as left side and some for right side, but I was thinking they are the same. I know the one on the passenger side has the ford part # DY832 (F88F-9F472-AB) That's the one that I have to replace, but I may as well replace both while I'm at it.
