The exhaust manifold studs are M10x1.25 right?

I just bought some new exhaust studs for my truck and I had a difficult time finding the correct length. Nothing at the parts stores was as long as the upper studs that the air injection rail bolts to. I ended up buying genuine Toyota studs. A local shop was able to order them from the dealer at their discount price of $1.63 each stud and $1.49 per nut. Expensive, but worth it in my opinion. The part number for the studs is 90116-10150 and the number for the nuts is 90080-17187. The OEM nuts look to be a lot better for exhaust conditions than the cheap nuts that the auto parts stores sell.
