Popped a shear pin on my blower and dug out the manual to order some new ones. I came across something I forgot I had. It's a listing of sears source prefix numbers and the corresponding manufacturers. It's from the antique small engine collector's club, might be usefull in tracking down parts. This is how I found my snow cab.

That one is much more informative. I think the antique engines guys were sticking to lawn and garden but this would really help out with all the craftsman , kenmore products around the house

I believe you can use the shear bolts from your MTD dealer also.
