1.5 hrs on the firewall bolts and parachute connection.

I found that a little persuasion with a large screw driver and mallet I was able to get the parachute tangs on the bolts.

Time to get the nuts on and torqued!  As you can see here I measured the friction drag to be 3Nm.  So, 16Nm (standard torque for an AN5 bolt) + 3Nm friction drag is 19Nm, which is almost exactly 14 ft-lbs.

And with a thin AN5 washer, 2 threads show, which is right in the preferred range of 1 to 3 threads.  A thick washer works best on the outer bolt since that bolt is longer (has to be since it also goes through the engine mount).

With new nuts on the bottom bolts, I also torqued those to 14 ft-lbs.

All done!
