The real question is: Does your local dealer have them in stock or would they have to be ordered if they break? Of course you don't want extra belts left over when you sell- the new owner probably won't pay what they're worth. Neither do you want to be down a couple of days waiting for a belt you knew was perhaps marginal. If the dealer doesn't carry them, you'll have to decide if you need the peace of mind, but I agree with the others- they'll probably make it. You'll be the first to know...
