It may not that be that big of an issue on a trail-mostly, two hard mounts only, vehicle.
I remember laughing at the factory "bushings" on my buddies '65 nissan patrol body mounts. It was a piece of 1/8" rubber just kinda laid there between the frame and cab.

when looking for a container to hold drained brake fluid, find a container that is different from the beverage you are currently consuming.
