I'm doing the engine/transmission mounts next and will definitely be using anti-seize compound on those.
On another note, I put a floor jack under my breaker bar to turn that nut. All it did was bend the bar! That's when I got out the angle grinder.
It just dawned on me that a crowfoot wrench set would allow me to torque the pinch bolts to spec. There is also one of the eccentric bolts on the right side that is impossible to get to with a socket due to clearance with the exhaust pipes. I have a cheap set on the way I got for under $20. I'm going to torque everything while I have it up on the ramps to do the mounts.
