LS4 Water valve control rod wanted

I managed to lose one of the two approximately 18" metal water-valve
control rods for my LS-4 (don't ask - its a long and embarrasing
story). This is the rod that extends from the pilot control on the
right side of the cockpit back to the bulkhead. I contacted the factory
(now DG) about obtaining a replacement and was told they are no longer
in stock, and re-manufacturing them will probably be prohibitively
expensive.

Anyone know a source (new, used, whatever) for this part? I guess I
could try stealing from another LS4 at a contest, but that could have
'negative consequences' ;-).

TIA,
