Does anyone know the size of the bolt/thread that goes into a revhard manifold? I'm looking for the one that mounts the wastegate to the top of the revhard manifold. I'm pretty sure they're all the same size, but I have no idea.

Try a couple random bolts you have around, then when you find the right one measure it.
On my Drag knockoff the wastegate bolts were 8x1.25mm

^ Yeah like I said.
But their mani-to-turbo doesn't match. On mine they were coarse thread, 10x1.5mm
For the mani-to-turbo studs just buy a length of ready rod and hacksaw it to the perfect lengths you need.
