I'll see if i can get my boss to order that die for a "job" he might sign off on it, if he does i'll let you know.

 

I was looking for the thread size on my rear cat as my sensor fell out of the pipe with the rusted out nut still attached to the O2 sensor, hanging by the wire! Made a new nut tapped it with M18x1.5 tap, welded in and problem solved.
Thank you
