Craig:

I considered testing the spring with a fish scale but I couldnt come up with a setup  to measure the deflection accurately.

If you have a setup that might get reasonable results, I'll be happy to mail you the new spring that Lancair sent me.  (need address).

BTW, Lee Spring sent me specs on 2 replacement springs;  one with a rate of 16.00 lb/in and one with a rate of 17.50 lb/in.  Unfortunately, they tag on a $ 20 additional shipping charge for any order less than 10 pieces.    BUMMER
