The Grumman C-1A was the cargo version of the military Grumman S-2 Tracker and did not have a tail wheel. The nose wheel on the C-1A model casters and uses differential brake steering with the left and right main gear. I only have the S-2 and the S-2T Trackers installed at the mo... and this is the config for the contact points to make the nose wheel steering active.
point.0 = 1.000, 14.087, 0.000, -7.868, 2950.000, 0.000, 1.050,
045.0, 0.200, 5.165, 0.800, 6.000, 6.000, 0.000, 150.000, 150.000 -- nose wheel steering
//for steearable nose gear, replace point.0 below with the one above; activate by removing the //'s
//point.0 = 1.000, 14.087, 0.000, -7.868, 2950.000, 0.000, 1.050,
180.0, 0.2000, 5.165, 0.800, 6.000, 6.000, 0.000, 150.000, 150.000 -- differential brake steering
Hope that helps...

EDIT: Here is the corrected contact point .0 for the C-1A:
point.0 = 1.000, 13.087, 0.000, -7.968, 1950.000, 0.000, 1.050, 045.0, 0.1500, 7.453, 0.900, 6.000, 6.000, 0.000, 150.000, 150.000, I believe that's pretty close.
