What o2 sensers of the 4 should I put in the Lts? I assume the back ones but I just want to make sure since there r no instructions. I was hoping there were some to let me kno the easiest way to put the Lts in, instead of me making multiple trips under the truck.

 

Front ones,how's the fit?

 

Just got them today before I had to go to work. Hoping monday I can get them in. Im welding in another o2 bung at the y-pipe, so later monday. Ill let u kno. thanks

 

fit is good other that the elbow on the drives side pipe that connects to the y-pipe need to be hit a few times. it was out of round a little bit, guess it was from when it was bent on the bender.
