Title says it all.

What is the thread size for the 3 studs on the top of the strut

M10 x 1.5 x 20 - 11561435

There's a chance it is this one:

M12 x 1.75 x 23.5 - 15815519


On mine, the same 3 nuts that secure the mount to the truck is the same as the one that secures the top of the shock to the mount.

When I recently replaced my struts the top nuts on the new ones were smaller than the factory ones but the studs were the same size so I kept the factory nuts to use on them and recycled the new nuts into my "Tahoe spare fasteners" washer jug.
