hi guys, does anyone know the size of bolt joining the up-pipe (or is it called the downpipe?!) to the turbo? One of mine is missing a nut that I want to replace, but can't figure out the diameter nut and pitch that I need. I know it's around 10mm/7/16" coarse thread, but can't quite figure it out. I'm pretty sure it is the same as this nut:

I can't find dimensions on the page, and need to get a nut on there ASAP
