Specifically where the downpipe connects to the turbo? I need to go buy a third nut that fits on there (not going to Mazda, I'd like to have the nut today and I'd like to not pay 5 dollars for it https://www.nopistons.com/forums/pub...DIR )

**** I could not find those at any local hardware store or big stores around here, and I hit about 7 stores. I had to goto the dealer to buy those, and I got bent over.

I think the pitch is 1.5 tho
