also needed to modify the rubber discs the seat on both sides of the mount.
the new mount (on the right) is different from the old one.
had to cut the bottom of the disc.
everything went back in place. installed the water hoses and new crash ring on the coolant plug.
the only hard thing in this job, was to torque the top left bolts that connect the mount to the engine. i used a crowfoot wrench attached to the torque wrench.
