I think the ones I used way back when were m8's. I probably still have a couple of the header bolts in my tool box. I'll see if I can find them an get the actual thread size and pitch. What is most important; since the turbo threads are stripped in most cases anyway, is that you get them far enough in to seat the non-threaded part of the studs tight against the turbo and get a nut on the bottom of them(they should have square ends so you can hold them with pliers or the right size socket while tightening the bottom nuts). Then you can slide the intercooler down them and nut em up from the top. The studs are hardened steel, so sliding the IC on and off won't chew the threads up at all. The header studs I used were found in the "HELP" section of an Advanced Auto Parts store.
