For those who want a gas spring back-up system:

I installed brass bushings in the nose gear tunnel at each end of the
over-center weldment (gm27) where it is attached to the nose gear tunnel.
 Then by using a roll pins to fasten the 'axle' rod (called a 3/8" steel
pin) to the weldment, I could place a pulley on the shaft(axle' rod) 
near the feet of the co-pilot.  A small SS cable rotates the pulley using
two 1/4 ratchets (cheap version) and a 1/4 inch extension about 12 inches
long (which the cable is rolled onto)  fastened to the fwd side of the
main spar with phenolic blocks (similar to the control stick cross-over
weldment).  To actuate: one reaches down between your feet and 'ratchets'
the gear down.  Either the co-pilot or pilot can do this since the unused
ratchet remains on the floor preventing the cable from unwinding and that
tension maintains the link in over-center.

Another possibility from bringing this link movement inside the cockpit:
mounting the gear-down switch in a cleaner environment.

My description seems confusing (as I reread it) so those interested are
invited to email for further clarification.
