426 Hemi Rocker Arm Shaft For The Intake Valve Rocker Arms, Wanted

I need a rocker shaft for the intake valves on a 426 Hemi engine.
Just need one.
A good used one is just fine, and ok with me.
It measures 19 1/2 inches in length, to determine between an intake, and exhaust, rocker shaft.
My missing one probably has been MIA since Viet Nam.
Anyone have just one lying around that your never going to use, that i can then have a 100% complete Hemi rocker assembly for the head.
Thank's.
