Default Wastegate Bolt Size

Just a quick quetion, what is the size of the bolts that bolts the gate to the flange. Its threaded for them. Its a Tial 38mm. Im about to reinstall the turbo but I cant find these damn screws, so Im hoping the local parts store has some that will do. Thanks

Well after looking for some random bolts i found the original ones!! SCORE! But ive seemed to have lost another part, one of my wastegates is missing the bost port. Since Im gonna run a dual boost setup, im gonne need both ports. Can I find a brass fitting that will fit this or what?

It's probably the banjo bolt type, not to easy to find, but you might get lucky at an auto parts store. You can just tap it for a 1/8NPT thread and just get a brass nipple from most any hardware store.
