Not to throw shade on your purchase, but in my experience Minnesota Outdoors (aka:Brad) is THE source for snowcat belting and knowledge.
I purchased some belts from him last year for a Tucker we were making some repairs to, and the entire experience was five stars. Great product, great price, great customer service. That's the trifecta of excellence for me.
There's a saying I heard when I was in the USAF and stationed in South Georgia: "Sir, I'd like the opportunity to earn your business". Sadly, many companies today don't have that philosophy, or even recognize business is earned. Brad "gets it", and I'll absolutely buy from him again.
