Drive Gear for AC 808 tranny?

[sidh]

My 1980 Allis Chalmers Garden Tractor has a broken drive gear. The mower repair shop that worked on it, removed the transmission info and so I don't have the model or number. I am looking for the gear so I can rebuild the transmission. The AC part number is 1657949-2. Is this a Peerless Transmission? Can anyone give me some help or point me in the right direction?
