Alright here is my issue....

The guy who re-welded my cat to bolt up to my exhaust welded it so the 02 sensor sits straight down and it scrapes sometimes when i go over big bumps and such, im gonna remove is permantely and just fill it in with a bolt....

Now does anyone know what MM bolt fits in that screw tap?

It would be greatly appreciated...

 

anyone?

 

i would go back to the guy who re-welded the cat to fix it.

i mean..seriously who the hell welds a o2 sensor striaght down so its like a big Hook waiting for it to get snagged on something?

but refereing to your question...sorry im not sure. prbably 14mm if i had to guess.

 

dan.. hell you get it off of the car and i'll see if i can grab the MIG welder and we'll put a short bolt in it and weld it up.. or i'll grab a scrap of metal i have and we can weld it up.

or you can just put a bolt in it.

 

well if i ever wanna fix it when im bored one day i can, i dont wanna weld it permantly shut...
