Tapered Bolts - Torque for Nuts?

How much torque goes on tapered bolts? I'll be using standard AN365 nuts, -3 for these. Does anyone have a table or a reference?

These hold the tailwheel housing to the tailspring on my RV-3B.

Thanks!

Dave

David, I used 15-20 in-lb for mine. I can not find the reference material for it. A nylock nut is required.
