I had to look at both a couple times before I noticed one says A/pin and the other says B/pin.
So my guess is that the drive pin on the 2 are different sizes.

What model do you have? A backdraft 8e right?

109 is the input driven by the driveshaft.<div></div><div>110 is the output which drives the dogbones/axles, 2 per diff.
