Hi all! Long-time lurker, have to say I love this site. I use it a lot for my 04 PAU, which currently is stock except for a significant maintenance update I'm about to finish (LIM, Water Pump, Plugs/Wires, and a bunch of other stuff).
Well...when I went to reinstall my Fuel Rail, I apparently overtightened the nut on the stud and it turned right off. Was even using a torque wrench although admittedly it likely was 1 or 2 pounds above spec.
I eventually was able to get the broken stud piece out...and now would like to replace all 4 of them. Problem is I cannot figure out the part # or a suitable replacement. Planning to go to the parts store after work and a hardware shop as needed to check sizes, pitch, etc.
Thought I would ask for help - does anyone happen to know the dealer part number by chance for either the stud, the nut, or both?
Thanks in advance for the help!

Haro - thank you very much, very kind of you! Followed quite a few of your posts, they are gold.
As silly as this sounds, since I'm so new the site isn't allowing me to PM quite yet. Let me engage in some more discussions and I'll surely send you a PM as soon as I can!

Additionally, if it helps anyone else, I was able to confirm the intake manifold fuel rail studs to be M6 - 1.0 at Autozone but unfortunately they did not carry the ones pursued.
