exhaust manifold studs..hard to find Options

[match220]

I've been trying to find studs to fit in my manifold for bolting on the turbo, I dug through the junkyard trying to find them, couldn't find any large enough. I ordered some m12 studs/nuts on ebay and got them in the other day. The problem I have now...the m12 studs don't slip through the turbo. Apparently I need studs that are half m10 and half m12. The m12 side bolts into the turbo side of the exhaust and the m10 studs slip through the turbo for the m10 nuts on the other side. I hope I"m making sense. Where do I get these? It was hard enough to find short m12 studs to screw into my manifold, now I have to find m12/m10 studs. Anyone have to buy these before?

Toyota has your parts.

No, they can't get gen III parts. I would have to order the same thing for the gen II 3sgte since toyota here doesn't have it in stock, then I would have to hope and pray that it's the same. I spoke with toyota yesterday, and they looked up the part for the gen II MR2, but they said it's not in stock, so they would have to order it, which means I pay for it even if it's the wrong thing when it comes in. They couldn't tell me the thread pitch or diameter of it because it didn't show in their system. And I've called nearly every other dealership on island and they can't lookup the studs by thread and pitch.

Can someone verify for me that the gen II 3sgte manifold to turbo studs m12/m10 are the same exact ones used on the gen III 3sgte?

This is a picture of what I need, It's a step down stud, one side is m12, the other side is m10. the m12 stud is too large to slip through the mount holes in the turbo, and the m10 is too small to thread into the manifold. This is a combination called a step down stud. I can't find the 1.25 pitch m12/m10 combo anywhere.
