Trying to get part # and order part for Snapper snow blower bought in 2004. Model # is 18245E. Current on line parts distributors are not recognizing model #. How do I get auger belt for model 18245E . 8 HP Briggs and Stratton 24 " 2 stage snow blower?

Hi,
The Snapper site has been having trouble with its own model numbers for a while now It is getting harder to find a site tying into ARI Network's site as well. I am going to guess it is part #7013937. The link I found is at:
