Ok, thanks. The other issue I have run into now is the "new" manifold is a used ats 3pc, the two studs in my factory manifold turbo flange don't want to come out, and the two bolts that were in it, don't want to thread into the ats right? Can I just get four new studs for the turbo flange? If so, where, or what are the threads to see if a fastener store would have anything?
