o2 Housing to Downpipe Stud

Does anyone know what the Tap size would be for the o2 Housing to Downpipe stud? I have a new stud but I need to rethread the hole.

Take the stud to a hardware store. Find a nut that threads onto the stud. Then find a tap that threads into the nut.

the stud is a 12x1.25

Yeah I knew the stud size, just was wondering if anyone knew off hand the tap size so I didn't have to do all that, but I can do that anyway. Thanks tho!

Are you just cleaning up the threads or did you have to drill it out? If you drilled it out, you'll need to tap it out to a larger size, get a larger stud and nut, and maybe have to drill the DP hole if the stud won't fit through.

Unless I'm misunderstanding you, the tap size is going to be the same as whatever stud you will be using.

But if the threads have been damaged you could do as kenamond suggested or helicoil it allowing you to retain the stock stud size.
