I think the OP means the spline interface between the back of the freehub body and the hub, not between freehub body and cogs. The link you showed matches that which the OP wanted, but appears to have the reverse bolt attachment, from the freehub side, the OP's bolt comes from the non-drive-side. However there is another on the page that might be match for the OP:

But note the cutaway of the spline protrusions near the base of the outside splines for the cogs; The inner cog will slip, unless it is held by a carrier.
