The clamp screw is safety wired. There is no brace to the firewall. No cracks after 2000 hrs. My backup plan was to attach two ¼ inch tubular braces running up to bolts on the oil sump, providing a triangular brace that moves with the engine. I was surprised to see how much a cross firing engine can move on its mount, rocker box covers can move well over an inch. I am not a fan of firewall mounts unless there is a flexible ball joint in the system. My crankcase vent is on the opposite side from the exhaust pipes. The engine occasionally blows a slug of oil out the vent (mild acro screw up) and I don’t want it near a possible ignition source, the belly is easy to clean.
