Snow B2550 Blower parts???

[DoktorC]

I'm helping peice my Grandfather's Kubota blower back together after an unfortunate encounter with a landscape rock. It seems that instead of shearing the shear bolt the sudden stop cause the gearbox to explode. I'm trying to locate just the casing OR the entire gearbox. The dealer told him it comes with the augers...which doesn't seem right to me.

Here is all the info I can find

The blower: B2550B

The gearbox:
Type: SG457a
Code: 45700100
Series: 1.98

P/N stamp:14570300

Thanks for your help!!
