I have a new Honda HS928TCD blower.  Apparently a change was made in the past for the shear pins for the HS928 so now there are two types available, depending on the frame serial number. The older style pins have a P/N of  95701-06016-00 and the newer style is 92101-06016-0A. Since I have a bunch of the older style shear pins, I am wondering what the nature of the change was and if the older type of shear pins will work for the newer model.  If the old style is used on the new frame type, is there a danger to the gearcase because the shearing point is different?  See  http://www.boats.net/parts/search/Honda/Snow%20Blower/0/HS928%20WAS%20SNOW%20BLOWER%2C%20JPN%2C%20VIN%23%20SZAS-1100001%20TO%20SZAS-1129999/AUGER/parts.html for the illustrations.  Any ideas out there?
