48" snow thrower drum gear

[Country Cadillac 0]

Hello folks.......Well I'm probably not the only one with problems with their equipment this morning. That storm we just had trashed the chain and drum gear on my snow thrower after just a short 36 yrs. in northern Vt. The chain I can get at the hardware store, but toro says the gear is NA. It bolts on with 6 bolts has 45 teeth and a 2 in. arbor hole. The snowthrower model # is 6-7451. Would anyone know where I could get one of these gears or would someone possibly have one for sale. Thank you very much for your time...................Ray
