ENGINE 912UL ... Model IV-1200

I have triple checked that all of the hardware is installed, and in the correct order, especially the steel bushings that are in the small rubber isolators in the interior of the engine mount adapter arms....

All is well, and all of the larger rubber isolators are inside the adapter cups...

PROBLEM: The Dec 2001 version of the firewall forward says to torque these AN310-6 Castle nuts on the AN6-31 bolts to 190 in-pounds, and I am at only 50 inch pounds and the castle nuts are going past the drilled holes in the bolt!

Any ideas?? Is the torque value correct?
