Well, this is what I need:
The 2 top rubbers (with steel support), 2 bottom rubber donuts, and 2 steel cups for the core support.
The 2 top rubbers (with steel support), 2 bottom rubber donuts, and 2 steel cups for the mounts behind the front tires.
The 2 top rubbers (with steel support), 2 bottom rubber donuts, and 2 steel cups for the mounts in front of the rear tires.
Unless I'm mistaken, all the pieces with the same name are the same.
So, 6 top rubbers, 6 bottom rubbers, and 6 cups. I think there are two or four more rubbers for the bed but I don't remember.
Does this sound accurate?
