Well I finally got my bad O2 sensor replaced today and the old one has a dent in it, is this normal

I know sometimes items are engineered that way, you know it looks like it has been damaged but then you find out its made like that to clear something, but seeing how an O2 sensor has nothing to clear, I think the O2 sensor was damaged during the "mystery mod" . That being said, I'm NOT, I repeat NOT, blaming the place who did this mod for me but rather letting you know to either take out the O2 sensors when doing the "mystery mod" or even better, just let THM take care of it

and I don't want to hear about how much he charges to do it either because I paid $135.00 for the sensor, labor and clearing/checking on the computer to have it done, not to mention the agony and pain I've been in since that damn CEL came on right after the exhaust work and that amount of money is about half of what THM charges to do it the "right, safe, and best" way!A side note to all of this is that the MIL eliminators that I bought from Dallas Mustangs are doing their jobs, and to think I was worried about that being a problem
