You have to go under the bus, after blocking it up safely, to look at what you have. There will be model/part numbers on the bag that needs replacing. You can measure also. One of your spares from the PO is likely the one.

The fronts are smaller than the rears on a 5A.  Sounds like you have a spare for the front and rear.

the smaller one is for the front, larger one for the rear.

those are goodyear numbers. MCI # for the front is 12c-1-35, or GMC #2292367 (60.11 ea. @ mohawk)
Rear= MCI # 12c-3-51, or GMC # 2292372 (67.27 ea. @ mohawk)
