I found two left and right side for $73.
Does post converter mean before the cats thats the front ones right???

 

no, post would be after

 

right after I sent that it hit me thanks though!

 

What is the best way to get the front oxygen sensor's out I tried going through the hood getting a wrench on the one on the passenger side but it looked like a good way to strip it out just wondering how you guys have got them out in the past?

 

I just changed all four of mine and I really didn't have a problem, only took about 45 minutes. The front set was a little more difficult and I had to use the O2 socket to break the passenger side sensor loose. The other three are reachable with a wrench (from underneath the vehicle), but your knuckles are in constant peril. Before you get started, drive the truck around to get the exhaust nice and warm, the sensors will break loose with a lot less effort.

 

Oh, and Atlantic British has the O2's for $59 each.

 

might soak some PB on them beforehand too...

 

OK whats the trick how do you unclip the post cat oxygen sensor passenger side my guess is remove exhaust pip? Or cut and crimp and shrink wrap?

 

I was able to get at mine w/ out removing anything.

 

The connection on the passenger side is the same as the driver side, it's just not as obvious. The connector is on top of the t-case. If you reach up there, you should be able to trace the wire to it. Just make sure that when you install the new one that you route the wire the same way. If you leave the wire loose, it could be snagged by your front drive shaft, and that would be bad.
