Highly doubt us in the colder climates will be able to hit 20 years with our harsh winters, but I've got a Yellowtop so I'll find out .

How did you mount yours? I see Odyssey has a cage system:

But I can't tell if that will work without modification in the FR-S. I see some aftermarket companies make super expensive ($150) mounts in aluminum but there has got to be something simple and cheaper than that. Ideas?
