DID NOT torque the nuts, yet. Mike Veth helped me fix one rivet on the bottom of the firewall. I had to drill it out to a -5-10. I then pop riveted 4 other holes that I couldn't get a bucking bar onto. They are not completely flush however, so I may have to grind them down some. Bolted the engine mount on to the firewall, and snugged the castle nuts. I did not torque them, yet, because it's likely I'll have to remove the mount in the future to make it easier to drill access holes through the firewall.
